Submarine Networks and the Digital Transformation of East Africa

Before 2009, only 16 African countries were connected to a submarine cable system.

But in 2016, submarine cable capacity reached 33 countries; seven sub-Saharan countries had access to three or more systems.

Today, Africa leads the globe in international bandwidth growth. This has been facilitated by improved international connectivity along the critical Europe-to-India-and-Asia submarine corridor that connects East Africa to the rest of the world.

Our own Paul Brodsky will be joining forces with Ciena and Djibouti Telecom on March 23 at 11:00 a.m. ET for a live discussion on this topic.

Submarine Cable Growth: Fashions from Yesteryear

We recently shared the pricing workshop and interconnection sector review our team presented at PTC '22.

But wait—there's more!

TeleGeography VP of Research Tim Stronge was on the scene to answer three questions about the submarine cable buildout boom.

What to Know About Fiber’s Role in Ukraine’s Information War

With all eyes on Kyiv, videos like this one from Ukrainian President Volodymyr Zelenskyy have made a monumental impact on the world’s ability to understand conditions on the ground.

Ukrainians are using their mobile phones to share the sights and sounds of Russia’s invasion, posting to platforms like Twitter, Telegram, and TikTok. These images may have already played a critical role in galvanizing public opinion in the EU, North America, and elsewhere.

How do tweets and videos from Ukraine reach the rest of the world?

Here are a few things to understand about the networks that have allowed Ukrainians to share their stories.

New State of the Network Report Examines Telecom in a Time of COVID-19

Believe it or not, with 2022 comes our fifth State of the Network Report.

If this is your first State of the Network rodeo, think of this e-book as an annual telecom check-in, informed by another year of data collection and analysis from TeleGeography’s larger research portfolio.

As usual, we extract the major global bandwidth headlines, take a snapshot of the global internet, peruse the latest in data centers, check in on the cloud, and finish with an update from the voice market.

There’s no other way to put it. This State of the Network Report is a weird one.

Love Is Brewing—and So Is Another Geomagnetic Storm

Happy Valentine's Day to you, beloved reader. Or Discount Candy Day Eve, as some of us like to say.

Love hurts, after all. But for a recently-launched fleet of Starlink satellites, a geomagnetic storm hurts even more.

How Well Do You Know Your Submarine Cables?

You're a master of our submarine cable FAQs. You know how many cables there are. You know how thick they are. You could take on the next generation of submarine cable experts in a head-to-head knowledge battle. 

It sounds like you're ready for the next level of cable know-how.

A Volcanic Eruption Cut Tonga's Only Undersea Cable Connection

Cable faults happen fairly often and for a variety of reasons.

Most of the time, damage to submarine cables comes from human activity—primarily fishing and anchoring. But environmental factors can also cause a cable to break. 

This just happened in Tonga, where an underwater volcanic eruption and subsequent tsunami damaged the country's only undersea cable. Early reports indicate that it could be a few weeks before the necessary repairs are made. More on that below.

Satellites and Submarine Cables: Myth vs. Reality

Next week our own Alan Mauldin is teaming up with Ciena's Brian Lavallée for a live presentation and discussion on satellites and sub cables.

You know how it works. We'll bring the data, you bring the questions. (And we'll all probably end up learning something new.)

Open Connect, the Red-Nosed Reindeer

It's that time of year again. The time to string up twinkle lights, pour eggnog in your coffee, and cozy up on the couch with your favorite holiday film.

Back in the day, you'd be dusting off the box in your attic marked "Christmas movies." Today—thanks to streaming services—all you need is your trusty remote.

But how does this actually work? Keep scrolling for insight on how Netflix delivers its content globally.

The Ocean’s Hottest Buoy Band

We at TeleGeography are a curious bunch.

So when we hear about an “ocean intelligence platform” employing a fleet of thousands of satellite-connected buoys, you have our attention.

Alas, the internet is teeming with other important news, so we’ll round out our November list of reading recs with cattle-monitoring smart sensors, a pricey USB-C enabled iPhone, the status of the $1.2 trillion U.S. infrastructure bill, multi-orbit satellite service testing results, and the relationship between 5G and climate change.
