Flashback Friday: Submarine Cable Repair in the 1980s

If you've read over our Submarine Cable Frequently Asked Questions, you know that cable faults are common. On average, there are over 100 each year.

Of course, as a society heavily dependent on these cables, we've gotten quite good at repairing them.

But what was the repair process like a few decades ago? How were we fixing cables back in the era of the Walkman?

Time for a trip down memory lane.

What Are Data Centers?

We're back at it with episode three of our five-part podcast special that explains the nuts and bolts of the internet.

You've come to the right place if you're looking to understand how all of those cat videos travel from the source to your phone. 

We explained in episode two how the internet is made of transport networks to carry data over (mostly) fiber optic wires distributed around the world. And in the episode before that, we discussed how the internet is a network of networks operated by thousands of mostly private companies.

But we haven’t yet covered exactly how and where those networks meet and exchange traffic with each other and access their destinations.

So today, it's data center time.

What is the Internet?

If you've caught TeleGeography's podcast, you'll know that we endeavor to explain the business behind human connection every week. We've chatted about Wi-Fi, WAN, and everything in between

We've audaciously called our show TeleGeography Explains the Internet, but we've never properly explained how the internet works and how bits get pushed around the globe. Until now.

That's right. We decided it was time to, quite literally, explain the internet.

Ranking the World’s Largest International Voice Carriers

Many retail service providers, such as mobile operators, MVNOs, and cable broadband providers, rely heavily on wholesale carriers to transport and terminate their customers’ international calls.

Wholesale carriers terminated approximately 257 billion minutes of traffic in 2022, down 5% from 2021. Wholesale traffic declined at an average rate of 1% per year over the past ten years, compared to a -2% CAGR for overall traffic. Wholesale carriers terminated nearly three-fourths (72%) of international traffic in 2022, up from 70% the year before.

Traffic to mobile phones in emerging markets has spurred expansion in wholesalers' share of the overall market. In 2022, wholesale carriers terminated over 87% of traffic to Sub-Saharan Africa and South America. In contrast, wholesale carriers terminated only 56% of traffic to Western Europe.

Wholesale revenues have changed only marginally from ten years ago. But let’s take a moment to look under the hood.
