- For
- Data-center buyers and infrastructure researchers in Japan
- Worth noticing
- The listings distinguish planned facilities from current ones and say unconfirmed specifications do not mean a facility lacks that feature.
Field notes
The catalog lets visitors narrow facilities by area, size, and cooling method, then browse 12 results per page. Sample records include operational details such as 7.6 MW IT power at KIX10, UPS N+1 at IIJ’s Shinsaibashi site, and an under-construction label for AirTrunk OSK1. The site says sources and confirmation dates are available on facility detail pages, and cautions that unconfirmed specifications should not be read as absent capabilities.
