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.

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.

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