Hello, gentle readers, and welcome to the 2025 State of the Network Report—our eighth edition.
The TeleGeography team spent the last year compiling market surveys, building algorithms, and analyzing emerging trends, and now we're ready to share the highlights.
Submarine networks enable uninterrupted connectivity among geographically dispersed physical data centers, effectively forming a global data center without walls.
Substantial investments driving the swift growth of AI infrastructure in both existing and new data centers are set to significantly influence data center interconnect (DCI) networks, which are essential for the success of AI applications and use cases.
Research Director Alan Mauldin recently joined Ciena’s Brian Lavallée for a live webinar exploring these technical and strategic drivers transforming the AI landscape.
Happy New Year? Now it is, because we just dropped our 2025 Submarine Cable Map.
Sponsored by Telecom Egypt, this futuristic, high-contrast design depicts 597 cable systems and 1,712 landings that are currently active or under construction.
Ah, São Paulo. A critical market for Latin American connectivity (just ask our Market Connectivity Score), and the perfect location for Capacity LATAM 2025.
With February right around the corner, many of us are gearing up to celebrate 20 years of Capacity Middle East.
The 2025 conference—held February 4-6 in Dubai—will tackle big topics like how the Middle East is preparing for AI, and how the industry recovered from February’s Red Sea cable cuts.
TeleGeography’s Paul Brodsky will lead a panel focused on the latter, looking back at the immediate implications of the cuts, and how different parties rerouted.
Another year, another African Peering and Interconnection Forum (AfPIF) keynote presentation for Senior Research Manager Patrick Christian.
His 2024 African Network Geography Update explored global network trends, as well as African bandwidth trends, interconnection hub trends, and end-user demand. There was a special focus on Kinshasa, where this year’s AfPIF conference was held.
What are the best-connected hubs in Africa? Where are new and planned submarine cables landing? Is intra-African bandwidth gaining traction?
Many locations around the world are clamoring to become the next great hub. But before we can identify successful practices to promote digital hubs, we first must decide how to measure that connectivity.
What role do submarine cables play? How about electricity and green power? And government policies ... can those even be quantified?
At Platform Global 2024, TeleGeography VP of Research Tim Stronge took to the stage to tackle these questions.
If you’re a regular on this blog, you're probably familiar with our submarine cable and cloud infrastructure maps.
But you may not know about the third tool in our interactive map tool belt: the internet exchange map.
The TeleGeography Submarine Cable Map is our longest-running map project. We started producing submarine cable maps in 1999, and we're still going strong 25 years later.
Just for fun, let’s compare the very first edition—called the Global Communications Cable and Satellite Map—to our 2024 Submarine Cable Map.
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 cables fixed in the era of the Walkman? Time for a trip down memory lane.
