My family has probably watched Lord of the Rings a dozen times or more1. We can (and sometimes will) quote entire passages from the films.
Latency is a term that’s frequently cited when discussing long-haul networks. But what is it really?
Subsea cables power the internet under oceans all over the world. But how many cables are there?
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.
We haven't been getting enough fiber here at TeleGeography Explains the Internet, but we're about to change that.
Nutritional jokes aside, this week, we welcome Todd Chapman, a veteran in fiber development, to the hot seat. Todd walks us through the ins and outs of Layer 0 of the physical infrastructure underlying data transmission. Some classic explaining of the internet.
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.
Earlier this week, operators of two communications cables—C-Lion 1 and BCS East-West Interlink—reported faults in the Baltic Sea.
Local internet service seems largely unaffected, but a swirl of sabotage allegations have emerged in the global press.
Without making a ruling on any ongoing investigations, let’s look at the facts.
We are now moving from sci-fi to reality with the launch of many AI services that are poised to transform industries and reshape our daily lives.
While data centers are expanding rapidly to support AI requirements, there is less clarity on how AI might impact long-haul network infrastructure, especially submarine cables.
This is exactly what I delved into during my keynote at Submarine Networks World 2024.
Sylvie LaPerrière, one of TeleGeography's esteemed partners, is a known tech leader in the digital infrastructure community.
You might specifically know of her work as a team lead for Google's subsea cable Equiano along the Western Coast of Africa. Or perhaps you know her as a renowned internet governance advocate and interconnection strategist.
We're so glad to welcome her decades of expertise to TeleGeography's Preferred Partners program. (This network of telecom professionals is like a telecom A-team ready to apply TG data to new and unique research projects. We're thrilled to take on new opportunities with them.)
Sylvie was kind enough to speak with our team about her take on the industry, advocating for women in telecom, and setting up her own consulting shop. Read our conversation below.
