DEAC is a data center located in Riga, the capital of Latvia and the biggest city in the Baltic nations. A region that doesn't have too many data centers.
The DEAC data center is an underground datacenter, located in a former bomb shelter under the Grizlinkalns park in Riga. DEAC's facility in the large bomb shelter features all the typical data center features and has a total capacity of 3x1Gbit/sec.
Converting existing underground facilities, such as mines and bomb shelters, to data centers is a rising trend, as it is a cheap way to get a secure underground facility compared to building one from scratch.
