Research & Education Networks, Topologies, and Trends

TeleGeography research groups bandwidth users into four categories: internet backbone providers, content providers, research and education (R&E), and enterprises and others.

Although R&E is often overshadowed—in favor of content providers especially—it is foundational to the other sectors.

The Intersection of Technology, Big Science, and Global Submarine Network Connectivity

We often overlook how critical submarine cable networks are in the advancement of scientific innovation. Their seamless connectivity enables data-intensive collaboration across research and education institutions around the world.

Next week, our Senior Research Manager Jon Hjembo and Ciena’s Brian Lavallée will dive into this topic through a live webinar: Big data. Big science. Big networks.

Escaping the Matrix: AI and Submarine Cables

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.

Once a Builder of the Internet, Now an Adviser to Future Builders

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.

International Power Plays on the Seafloor

Undersea geopolitics and digital sovereignty are the buzziest of buzzwords as of late. So it's no surprise that the politics of subsea cables are on the agenda for Submarine Networks World 2024.

Business Broadband in Africa: Notes From My Summer as a Research Intern

As our summer internship session winds down, TeleGeography welcomes summer pricing intern Zar Adisuryo to the blog! Zar just graduated from Georgetown University with a master's in communication, culture, and technology here in Washington, DC. 

We had the best time with her intern class in the office; our interns are an asset as we compile large, data-intensive research projects throughout the summer. Today, Zar shares what she's learned about broadband in Africa while on the job.

We'll pass the baton to Zar to tell you the rest. ⬇️

That's Great, It Starts With an Earthquake

We started collecting our monthly dose of telecom reading recommendations when it occurred to us: this reading list is somewhat despairing.

Earthquake-based cable outages, infrastructure security concerns—a headline that literally includes the words "solar catastrophe." We don't mean to bring the room down with our July picks, but maybe have something lighter queued up for later.

A (Refreshed) List of Content Providers' Submarine Cable Holdings

For the last eight years, we've posted submarine cables owned by content providers over here. (Shout-out to the readers who had this one bookmarked.)

When we first published this list in 2017, we had 20 cables listed. Fast-forward to today, and our list has grown to over 60—a sizable markup.

With such an uptick in content provider cables to track, we figured it was worth starting a fresh new list for you to bookmark.
