Our newly updated Global Bandwidth Research Service shows that the global bandwidth market is still experiencing massive demand growth.
Between 2019 and 2021 alone, international bandwidth used by global networks doubled to reach nearly 2,900 Tbps.
So, who's driving all this demand growth for international capacity?
Ah, the great Atlantic.
It's the world's second-largest body of water and the most heavily trafficked route in terms of submarine cable capacity.
It also happens to be TeleGeography VP of Research Tim Stronge's favorite ocean.
Tim told us as much during a recent Ciena webinar, where he gave a live presentation all about the Trans-Atlantic Submarine Corridor.
Earlier this year, TeleGeography VP of Research Tim Stronge gave a very fashionable presentation on the submarine cable buildout boom.
Tim's presentation zeroed in on bandwidth demand—or more specifically, what's driving it? Now it’s time to focus on where innovations are happening the fastest: the Atlantic.
OnJune 2 at 11:00 a.m. ET, Tim will meet with experts from Ciena and Lumen for a live discussion on how submarine networks can scale to manage this surging demand.
If you've seen our famous Submarine Cable Map, you can probably guess that the TeleGeography team geeks out on submarine cable knowledge.
And although there's a lot to know, we still get excited when cables come up in the news.
So it’s no surprise that our latest list of telecom reading recs starts off with a story about submarine cables—and their potential to detect earthquakes.
Have you been playing the secret cable trivia hosted on our interactive submarine cable map?
If you haven’t, look for the icon in the bottom right-hand corner of the map. Submit the correct answer and you’ll be entered to win a free submarine cable map in our monthly drawing.
In February, we released the answers to our first three questions. Now it’s time to reveal a new batch of answers.
We've discussed the ways in which the WAN is moving away from private networks and MPLS in favor of reliance on the public internet. Not to mention the costs and benefits of that evolution.
Although it's certainly always been the case that WAN managers must stay on top of internet performance and outages, this is increasingly crucial in the internet-first WAN era in which we find ourselves.
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.
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.
