What if I told you the world's biggest companies don't use the internet like you and I do?

They have a direct connection to each other.

They're neighbors, bypassing the big bad wild internet.

And they do that here.

This is where the internet lives.

This is the Dallas Info Mart.

1.5 million square feet of data center goodness.

8,700 strands of fiber, multiple internet exchanges, over 140 networks peering at terabit speeds.

It's one of the most connected buildings on earth.

In fact, if you're watching this video from here, your packets are likely going through this building right now.

So let's try and get in there.

Get your coffee ready.

We're going to go play inside a data center today.

It's going to be kind of crazy.

Look at all these timestamps and covered a lot.

Let's go.

Yeah.

I go into the info Mars.

Now getting inside a data center is hard.

Security is intense.

They got multiple layers of protection and it makes sense.

I mean, they're protecting billions of dollars worth of equipment and a large chunk of the internet.

You can't even get past reception without a being a customer or B being invited.

Thankfully, we didn't have to social engineer our way in there, putting on a hard hat and a vest and pretending we're important.

Although I'd like to try that one day, actually.

Ethically, of course.

But today, we're invited.

Or I use my YouTube powers to ethically hack with my influence.

Go with that, it sounds way cooler.

But seriously, Equinix invited us out and made this video possible.

Thank you, Equinix.

So this is actually one of their data centers, and this is one of their people, Sal.

Hi, I'm Sal Gonzalez, senior manager of Global Technical Sales.

Been with Equinix 24 years here in Dallas, Texas.

I tricked Sal into letting us follow him into the data center.

Now after me and my team signed in at the first checkpoint, supplying our IDs, getting a fancy name tag, we then encountered the man trap.

Not just anyone can go into a data center.

You have to have access, key card, thumbprint, and go into a man trap.

Or person trap.

This is the fanciest one I've ever seen.

Come on in.

It's a trap because once you arrive inside, both doors have to be closed before the other one opens.

Then you have to authenticate on this side too to open the door and now we can get to the data center.

Now, this prevents a very popular form of physical security hacking known as tailgating or just following someone in, grabbing the door before it fully closes, which is kind of what I did following Sal in, but he let me.

But normally that does curtail this quite a bit.

And it's hard to stay under the radar

when you're awkwardly standing next to someone waiting for them to open the second door.

It becomes a bit obvious what you're doing.

This man trap, like most you'll encounter, is a security measure ensuring only authorized individuals enter secure areas.

Now, once in, we're being watched at all times.

Not just cameras, but we had to be escorted everywhere we went.

I couldn't even go to the bathroom without Sal.

I also couldn't get coffee without Sal, so I begged for coffee and he took me to the break room, which is actually kind of fancy.

They had fancy seltzer water, coffee was just okay.

I should probably help them with that.

Why don't I sell my coffee to data centers?

I'm gonna write that idea down, actually.

Now, at this point, we're still not in the data center.

I don't hear that sweet, sweet sound of whirring servers, but we're about to be.

But first, we encountered yet another door that required another badge and fingerprint.

This place is secure.

But why that extra door?

We already authenticated, right?

Yes, but there's layers.

You see, as a customer at that data center, you are only given access to your stuff.

The floor your stuff is on and the cage your stuff lives in.

Yes, there's another area that requires another badge and another fingerprint.

It's insane.

But then we saw this as we were walking through those doors.

I saw a customer wheeling in a massive rack of servers.

And here's an example of the customer that is bringing in a 40-loaded rack.

That's an AI customer, isn't it?

Do you recognize that customer?

It's Grok or Grok.

I'm not sure how to say they are an AI company and those racks were dripping with LPUs.

Oh, I was kind of freaking out.

I couldn't stop smiling.

And we actually had to ask permission to even mention that we saw them.

And that's what's so cool about being in this data center.

Major companies, companies that we rely on for core services.

They're here.

This is where they put their stuff.

This is the internet.

When we're asking AI a question, it's answering it right there.

When we like a video on YouTube, actually go ahead and try it.

Hit the like button.

Watch.

You're gonna make that server smile.

Ready?

See, there it went this is the internet i need calm

down a little coffee break now getting back to security i

looked at a lot of server racks as we walked by

because i'm always curious what people have

but what i didn't see was any indication of what company these servers belong to

and that's by design just walking past these racks

if you happen to notice a company you're familiar with

and seeing what servers and networking harbor they use those are some trade secrets

and then equinix takes it a step further notice the lights

in this place they're blue why is almost every light in the in the Equinix data center, blue.

100

It makes it colder in here.

101

No, that's not true.

102

There's two reasons they have that.

103

One, it's just fun.

104

RGB, we do it to our gaming machines and they do it to data centers too.

105

The field was supposed to be kind of a nightclub.

106

You got black walls, blue lights, video games in the conference rooms.

107

The second reason is that it's kind of secure, or at least it used to be.

108

Having blue lights made it harder to read the labels of the people's equipment in the cages.

109

If you happen to know that a customer used F5 and you're a competitor, hey, I might want to use F5.

110

They're using Cisco.

111

I want to use Cisco.

112

I want to have a competitive edge.

113

And I kind of like that.

114

Just It's another subtle form of security.

115

And if you're new to security, stuff like this is key.

116

Multiple layers, defense in depth.

117

Don't rely on one solution, one method to secure your stuff.

118

Use multiple layers.

119

Now, one thing I wanna point out, that company Grok, which by the way is not XAI Grok, it's this Grok.

120

They're wheeling in racks of servers.

121

Back in my day, when I was a network and systems engineer, we would be assigned a rack in a data center

122

and we'd have to bring all of our stuff with us to that rack and then rack it and stack it ourselves.

123

I still have scars from the cage nuts.

124

Look.

125

But when you're working with Equinix, it's common to have all your stuff pre-configured and they do the rest.

126

Now look at these cages.

127

This is something I wasn't used to.

128

When I would walk into a data center, I would just see rows and rows of server cabinets that I could just walk up to and open most of them.

129

Anyway, not great for security.

130

I like what Equinix does here better.

131

When a customer puts their stuff into a cage, usually only that customer has access to this cage fingerprint badge.

132

Unless you have that, you're not getting in there and look at these cages.

133

Not all of them are the same.

134

And I thought this was so interesting because some have an open top.

135

So in theory, I could climb that cage and get in there Tom Cruise style.

136

I asked him if I could do that or if anyone would catch me if they weren't looking.

137

They're like, no, we're always looking and we would catch you within five seconds.

138

Securities, watch it.

139

So if you want to get tackled by someone.

140

Noted.

141

But other cages, they actually have a closed top and some I couldn't even see.

142

They were in enclosed areas.

143

Some customers are also not additionally just to the deck there.

144

They actually put the mesh underneath that as well.

145

And it's fully enclosed.

146

Top secret.

147

I wasn't allowed in there.

148

Still bummed about that.

149

I would imagine there are some crazy top secret companies in this data center.

150

There's gotta be, and it's kind of cool.

151

If you need top secret stuff, Equinix will give you what you need.

152

Customers can also put whatever security they want.

153

And unless there's some kind of crazy security issue, Equinix will not even go into your cage.

154

This is your cage.

155

Here I'll fight in here.

156

It's going to deny me because I am not the customer of this cage.

157

Now speaking of security, what about the people like the people who work there?

158

I actually learned that becoming an Equinix technician is no joke.

159

This is Manny.

160

He started as a tech over 20 years ago.

161

I've been with Equinix 24 years, going on 25 years in July.

162

I'm a sales engineer, started as a tech for 8 years here at the data center, day one.

163

A site engineer, I was on sales team.

164

Sales engineer for 8 years, so that's the combined 24 years.

165

And this is part of their interview process.

166

They took me to this other building and they had this rack where you had to actually go through a test.

167

Building cables, running fiber, splicing.

168

Cool.

169

Because a lot of people in the interview can talk.

170

Oh, I got my CCNA.

171

I brought problems just up to date.

172

Yeah.

173

Yeah.

174

And then it's like, they get in there.

175

I fall.

176

Yeah.

177

I can even do an RJ 45.

178

So what I'll do is break the fiber, unplug it somewhere and break that, that circuit.

179

Now something had me wondering, I saw all these grok racks being wheeled in.

180

You gotta know they're just dripping in.

181

How in the world do they power all this and how do they cool it?

182

Because I don't even keep my gaming machine here in my studio.

183

I used to get way too hot.

184

So I keep it in a cool server room.

185

Imagine an entire rack of GPUs and not just a rack, a data center full of GPUs.

186

And then I saw this look at the floors.

187

Yeah.

188

Go ahead and look.

189

Do you notice something weird?

190

They're not raised floors in a typical data center.

191

You have a raised floor and they actually pump cool air in from the ground because you know, hot air rises.

192

This place didn't have that.

193

How are they, how are they cooling this stuff?

194

This facility we've evolved to pushing air from the side and the hot air is actually pushed up and out through ventilation.

195

So typical hot air rising situation.

196

This is the air handler pushing it to the side, goes up to the top, it still comes back, but now it's being flooded.

197

The room's being flooded to the side.

198

Now I ask Sal which is better, the raised floor or the way they do it pushing air from the side.

199

We can argue to where the blue of those lights, it's just a preference when it's all said and done.

200

They use slab floors because it can hold more weight.

201

Those server racks are heavy.

202

Now on every floor they have air handlers at the end of the hall that cool everything.

203

But the power of this is on the roof.

204

And the way they cool this data center is kind of like a gaming computer.

205

Hear me out.

206

It's like liquid cooling.

207

On the top, you have your radiator, like your gaming PC.

208

You normally mount your radiator and the fans to the top.

209

You'll have your water or your liquid go to your radiator, get cooled off by the fans, and they get pushed back down to your GPU or your CPU to cool it off.

210

And as the water gets hot, it goes back up and gets cooled off again.

211

That's what's happening here.

212

All these things are doing that.

213

And what's crazy is that each one of these containers is self-contained.

214

Meaning when they want to add another one, they just airlift it in there.

215

Boom.

216

All in one go.

217

They also have giant water tanks.

218

That's kind of a buffer.

219

In case something fails, I got some backup water to go in and cool things off.

220

But what if the power fails?

221

They got a backup for that.

222

Their generator yard is insane.

223

All right.

224

We're able to run on diesel generators for a total of 36 hours at full load.

225

Yeah, everything here 36 hours.

226

Yes.

227

Wow And if for some reason we're not at full load, and obviously we have more runtime back on the roof It

228

was kind of funny Ed hi Ed He was very afraid of heights, but he went up there for us didn't get anywhere near the edge

229

But I'm proud of that now enough about power and cooling

230

and all that like that's fun And you can go watch this guy cuz he talked about it more, but I want to talk about bypassing the internet Let's go there right now get your coffee ready.

231

I'm already kind of hyped up today Now this part is actually kind of crazy

232

and it has everything to do with that dystopian mall across the street You'll see.

233

But first I want to talk about the problem this data center and it's dystopian mall are solving.

234

Most people and businesses connect to AWS GCP, Azure for stuff, the stuff we use on the internet, because that's where the internet lives.

235

And it's critical, especially for businesses, because they'll often host their infrastructure up there in the cloud.

236

But they also might have some stuff back in their data center and doing a hybrid cloud situation.

237

So that connection, dude, it can't be crappy, but often it kind of is.

238

We're usually connecting through the big, bad, wild internet, hopping between routers connections with potentially bad latency and frequent drops.

239

It's kind of like going on a road trip.

240

You can't guarantee the quality of the roads.

241

You don't control any of that.

242

And you never know when there's going to be traffic.

243

That's the internet.

244

That's why things are slow sometimes.

245

But Equinix, they flip the script on this.

246

They help people skip the internet.

247

And it's because they're so well connected.

248

Remember, this is the most well connected building on earth.

249

And we're talking about two buildings, not just one.

250

The main data center is known as DA11.

251

It's flashy.

252

It's fresh.

253

It's ready to host all your crazy AI workloads.

254

Across the street is something a bit older.

255

This is the Info Mart, the most interconnected data center in the Southwest.

256

Let's go.

257

It's DA1, known as the Info Mart.

258

It's kind of pretty, though.

259

Got that retrofuturistic feel.

260

It's kind of my vibe.

261

It was built in the 1980s, and it was modeled after the London Crystal Palace.

262

And it was supposed to be something like Tony Stark would think of, a technology mall where companies like IBM and Kodak would have storefronts, permanent showrooms to show off their cool stuff.

263

But it was kind of ahead of its time, and it didn't take off.

264

So now we're left with this big, large, gorgeous building that happens to be sitting right on the middle of the Internet superhighway.

265

This is one of the most critical items

266

and pieces of the building itself is just the amount of network fibers

267

that come in here and dark fibers that come in here.

268

This is ultimately what makes Equinex, Equinex, which is a network connection hub for the world.

269

Like, I'm not even kidding.

270

Location, location, location.

271

This thing is sitting pretty.

272

It literally is a fiber highway because in the U.S., long-haul fiber cable was often laid along existing rights-of-way, primarily railway lines and existing highways.

273

The Info Mart is sitting right there at a major convergence

274

of some fiber optic highways is grand central station for the internet

275

but this actually kind of became a problem these major connection

276

points these internet exchange points were often controlled by a single large telecom company

277

and they called all the shots dictating who could connect

278

and at what price the equinix they weren't about

279

that they actually pioneered the idea of a carrier neutral data center

280

and they said hey anyone can come in level playing field we don't care who you are

281

so it kind of works like this let's say AT&T wants

282

to connect at the info Mart they put a network node in there makes sent this prime real estate.

283

AT&T has all the connections, but you know what?

284

Verizon wants in too, and they can, they jump in and they connect and they Lumen once in because they realize how valuable this real estate is.

285

So now they all have network nodes there and they kind of snowballed from there.

286

The more networks that joined, the more valuable this building became becoming one of the most network dense buildings on the planet.

287

And that sentence just felt good to say coffee break.

288

Okay.

289

What does it have to do with our story though?

290

Well, Equinix bought that building like it's ours now and we're gonna let everyone come in.

291

This happened back in 2018.

292

And then they have another building right next door.

293

Then they ran a massive fiber highway underneath between the two buildings.

294

So if you want to connect to a network or a cloud, it can all happen right here.

295

It's just a cross connect away.

296

Okay, cool.

297

Lots of connections, but that's not all the equinix is doing here to see the next part.

298

We needed secret access to one of equinix is own cages.

299

Now I said a word before that you may not caught cross connect.

300

What is that?

301

It's a common thing you'll do in a data center.

302

So let's say you and I, we start a company network, Chuck.

303

Coffee, of course, and we put our servers in a data center, but then we're like, Hey, we want an internet connection.

304

And let's say we go with AT&T, AT&T will have their network stuff, their telecom infrastructure in another cage somewhere in that data center.

305

We have to somehow get a connection to their stuff.

306

So we have internet.

307

So we'll order one, we'll order a physical cable that will connect our stuff, our router, our switch, whatever it is to AT&T's cage.

308

That cable is called a cross connect.

309

And you normally have to do this for whatever thing you want to connect to.

310

So maybe AWS, you want to have a direct connection to AWS.

311

You can do that because Equinix has everybody in there.

312

You can order a cross connect, get a cable, go straight to AWS, Azure, GCP, whatever you want, but these are expensive and they take time.

313

You have to order these months in advance.

314

Time is money.

315

But now back to our cage right here is housing something that I thought was the coolest idea ever.

316

It's called fabric.

317

Instead of getting a million cross connects to all the companies you got to connect to, you just get one connection.

318

So this is Equinix Fabric.

319

This is something we designed over 10 years ago.

320

We were founded with Internet Exchange or IX.

321

That's how we got started, where people would literally do cross-connects.

322

So it was a one-to-one connection where they connect from one customer over to another customer.

323

And then we'd have everyone together like in a data center so they'd be in close proximity.

324

So we developed Fabric in a way so now you can just get

325

that one port and you can create multiple virtual connections

326

so now you can have all your cloud connections you can

327

connect to other service providers with us other network service providers

328

uh other people like zoon etc they're on our fabric over 3 000 other customers today

329

and you can connect to them within seconds now you don't have to go

330

and talk to someone else to get a cable connected over to you can just go connect to them virtually

331

and you can go anywhere from 10 megabits up to 50

332

gigabits it already sounds cool let me Let me hit it home real quick.

333

Imagine you order a 10 gig connection from Equinix fabric.

334

You can virtually segment that connection.

335

However you want.

336

Let's say you want one gig to AWS straight to their cage.

337

How about one gig to Azure one gig to GCP let's use two gigs for AT and T internet, maybe one gig for Verizon for backup.

338

This is all happening in a portal.

339

You're just clicking.

340

You're not running cable.

341

How cool is that?

342

Now the way fabric does this is with something called software defined networking, a fancy buzzword.

343

That means you can do a lot of what we used to do physically inside software, making it super easy for us now.

344

So in this rack is where all that's happening.

345

Notice a lot of Juniper equipment.

346

I'm a massive fan of Juniper.

347

Now I don't want to oversimplify it, but it's kind of like connecting to a switch along with every other company there.

348

You get a super fast, low latency connection with security, obviously.

349

But just sit back and think about that for a second.

350

With the racks of equipment you see here, Equinix is giving you access to all the major companies and cloud providers.

351

And it's not just the companies connected to the hauntingly retro building across the street.

352

InfoMark.

353

Major players also run fiber directly from the street, from a manhole dark fiber into da 11

354

and major companies might have a presence on multiple floors this

355

is one of those rooms where dark fiber comes in look at all

356

that fiber they were kind of hesitant to let us in there

357

but they did me a solid let me just check i think i have access let's see

358

look at that

359

and that's the theme here connection connection connection like most data

360

centers they have one room in the data center called a

361

meet me room where all the network providers come in

362

and they're all just sitting there in a closet huddled together saying connect over here equinex doesn't play like that.

363

Like every floor is a meet me room.

364

Now, hold on.

365

I know what you're thinking.

366

You're thinking about fabric and how sure they give us a direct connection to AWS GCP

367

or Azure right there in that data center.

368

But what if you're trying to access AWS from another location, like AWS and GCP and all these guys have multiple locations in other data centers.

369

What if your stuff lives in Virginia or Washington or New York or California, then aren't you having to go across the internet anyway?

370

Actually, no, you're on Equinix is stuff.

371

Now Equinix has data centers, stinking everywhere look at all this look at all these data centers look at this map

372

so when you hop onto their network you're on their network the equinix internet

373

and you're taking that special hov lane vips only now me

374

and my team spent all day at this data center two incredible buildings

375

and we learned like how they work what makes them tick

376

but you know what it's not the security or the power

377

or even the insane amount of connections

378

that stuck with me what makes this data center run is the people these people

379

that were walking us around they were humble

380

and awesome they've also been there forever some of them for over 20 years

381

that tells you a lot about a company by the way

382

if you want to know

383

if a company is good look at the tenure of their employees

384

so while it was cool walking around and seeing all the amazing things

385

and geeking out what was probably more fun was just getting to know these people the people

386

that make the internet run because

387

when you get down to it all the tech we encounter all the things we do there's people behind it

388

and normally how awesome a product is correlates how much passion the people pour into it

389

so when you're surfing the internet that today, when you ask AI a certain question, just pause for a moment.

390

Think about Sal.

391

So thank you, Sal, for making this possible.

392

Manny, Brad, Ed.

393

Also say thanks to Ed and Jordan.

394

Like right now, they were the ones who organized this whole thing and they waited forever for me to make this video.

395

And we're so patient.

396

So if you could just like right now in the comments say, thanks, Ed and Jordan, it might convince them to show us something crazier for the next video.

397

Anyways, that's all I got.

398

I'll get you guys next time.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
