Content delivery networks (CDNs) are a geographically distributed network of servers (caches) that work together to deliver content by moving it closer to the end-users.
In early 2022, AWS announced a new element to its cloud network infrastructure: the local zone.
With increased focus on moving cloud services closer to end-users, the local zone provides low-latency access to applications running closer to customers.
Google offers a similar service with its dedicated interconnect service, an option to connect to a low-latency colocation facility that provides latencies of less than 5 milliseconds between the workloads in a specified region and the on-ramp location.
OVH launched the same local zone service in the first quarter of 2024, and Microsoft joined in as well with their extended zone service launched in the summer of 2024.
Here's how these services differ—and how many have launched.
In 2024, 13 new cloud regions were launched globally. This marks a significant slowdown in the deployment of new cloud regions.
There hasn't been a year with fewer than 20 new regions since 2017. As you may recall, 26 regions launched in 2023, 24 in 2022, 27 in 2021, and 25 in 2020. At the peak in 2019, 41 regions came online.
From cross connects to PUE, the data center industry is packed with technical jargon.
Today, we’re breaking down 13 key colocation terms. Whether you're new to the field or just need a refresher, this simple glossary can help.
What makes a city a hub? And what makes a hub healthy?
Before we answer these questions, we must acknowledge that the interconnection market is not a homogeneous thing. It's an ecosystem comprised of numerous critically interdependent parts, much like a body or a machine.
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.
In November, we unveiled our new Market Connectivity Score (MCS) and dropped our first public rankings of the top ten most connected and fastest-growing cities in the world.
Because we update the MCS quarterly, it's time to see how those rankings have changed.
Happy holidays, TeleGeography Explains the Internet listeners.
We hope you're savoring the brief week between Christmas and New Year's when the world takes a moment to pause and reflect. School is out, schedules are topsy-turvy, and cookies are acceptable for breakfast. Perhaps like some of us, you've lost track of movies watched and presents wrapped.
If you're looking to take a break between the winter gatherings, grab some headphones. We've got you covered for an hour or so.
Last month, I had the pleasure of speaking at Cairo ICT about colocation and connectivity trends.
I covered global bandwidth first, followed by a rundown on bandwidth in the Middle East and Africa.
Next up, data centers and interconnection hubs, with a discussion on where the hubs are, what makes a hub, and how hubs grow. Finally, I talked about end-user demand, which is very important with the growth of internet and demand.
