We're pumped to have Dennis Thankachan, Co-Founder and CEO of Lightyear, back on TeleGeography Explains the Internet.

Last time Dennis joined us on the show, we dug into Lightyear's approach to creating a digital telecom lifecycle automation platform for enterprise networks.

This time, we discuss their State of Connectivity Report, which dovetails nicely with many of the issues we research here at TeleGeography. (Perhaps this read is a perfect companion to our State of the Network? A match made in heaven, etc.)

TeleGeography’s Submarine Cable Map recently hit a new milestone: depicting over 650 cable systems.

As of February 2025, that’s a whopping 570 in-service systems, with another 81 planned.

The number of cable systems we study is constantly increasing. This is due to massive investment in this infrastructure—both along major routes and to small islands—as well as our ongoing efforts to track global systems in more detail.

A few weeks ago, I returned to sunny Honolulu for TeleGeography’s annual telecom trends workshop at PTC.
