How reliable is the multiplayer service?

Over 25,000 people use the SparkChess Multiplayer service every day. There are between 300 and 1000 players online at any given moment.

We have load-balanced live servers located in New York City with automatic  failover located in Seattle. We use Cloudflare for quick delivery, firewall and DDOS protection. We take daily offline backups. The quality of service is monitored 24/7 at 1 minute intervals.

Unlike many other MMO’s we do not take servers down daily or weekly. We apply rolling updates on the servers so that there’s always at least one server running at any time. We have 99.999% uptime and we’ve been this way since 2012.
