Frequently asked questions
- How many connected datacenters are in Japan?
- 58 facilities show an active or dense connectivity band, 35 of them dense.
- What is a connectivity band?
- A verified summary of network density. Dense means many networks, exchanges, and carriers; Active means multiple networks or an exchange on-net. The exact counts are part of the paid operator dossier.
- Why does carrier density matter?
- More carriers present means more route redundancy, more price competition, and lower latency to reach networks — the core reason network engineers shortlist one facility over another.
