ICYMI: we recently launched a dynamic new tool called the Market Connectivity Score (MCS). 

The MCS is our answer to the question “Where is the next big hub going to be?” and pulls from our wide array of research areas to evaluate the health of more than 3,000 metropolitan markets worldwide.

Today, let's take a brief look at three of the markets highlighted in the MCS: Frankfurt, Singapore, and São Paulo.

As a new year approaches, so does our annual workshop on all things telecom.

At PTC ’25, Brianna Boudreau, Jon Hjembo, and Alan Mauldin will return to the conference stage to share fresh insights on pricing, interconnection, submarine cables, bandwidth, and more.

A big part of last year's conversation revolved around resolving the delays in new network supply that had plagued the industry for the last few years, and assessing the “new normal.”

Here’s what the TeleGeography trio will dive into in 2025.

Our Data Center Research Service estimates that there are 24 metropolitan markets that have more than 1 million square feet of operational data center capacity and four-year CAGR of at least 10%.

Nine of those 24 markets are in Asia and seven are in Europe. Even more extraordinary—four of the Asian markets are in India alone.

The data center market is in the midst of an unprecedented shift that started—publicly at least—five years ago with the announced moratoria on new development in Singapore and Frankfurt. Those regulatory interventions highlighted the challenges the industry faces in securing sufficient power.

Since then, it turned out that data centers would need much more power than had been realized—just at a time when regulators and community organizations were growing increasingly critical of the sector's existing demand.

Our Data Center Research Service estimates that, as of 2024, colocation operators in the top ten data center markets by MW consume about 13 gigawatts (GW) of power.

That's enough power to generate electricity for roughly 10 million homes—or, in this case, only about 1,000 commercial data centers!
