Monitored by StatusCake

SparkChess Multiplayer is hosted by leaders in cloud servers. We have load-balanced live servers located in New York City with automatic  failover in San Francisco; we take daily offsite backups; we monitor the service 24/7 at 1 minute intervals. We have >99.999% uptime (less than 5 minutes of downtime per year!).

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

If you get disconnected, the most likely cause is an instability of your internet connection – wifi issues, mobile data connectivity and so on.

If you have any problems with the connection, please check our FAQ.

A routine server update caused an error in the multiplayer service due to a timezone incompatibility – the new database server did not recognize the old timezone code. We diagnosed the issue and deployed a hotpatch in 20 minutes.

October 5, 2020

The multiplayer service is currently unavailable. We’re working as fast as we can to identify the problem and restore the service.

UPDATE: Service restored. The outage was caused by service misconfiguration. We’ve added internal procedures to prevent this event in the future.

A minor hiccup caused some of the multiplayer users to be routed to a “hot spare” server. About 200 players experienced a brief disconnect. We hope this hasn’t caused any inconvenience as games should have resumed automatically. If any game was affected, please contact us and tell us your name and your opponent’s name.

We’re under a heavy DDOS attack that’s affecting the multiplayer experience. We’re working to mitigate it and we’re very sorry for the inconvenience.
UPDATE 21:30 GMT – The whole NYC datacenter is affected by this attack. We’re working with our host to mitigate it.
Update 23:00 GMT – The situation appears to be resolved.

Jan 8, 2020

Our host is planning a network reconfiguration on January 8 at 8:15 PM GMT-5 for about 5 to 15 minutes. Service interruption should be minimal since SparkChess has built-in redundancy, but we will monitor the situation closely in case reboots cause any issues.

Update: The operation completed successfully. Multiplayer users experienced a brief disconnect as they were reconnected to a different server.
