Service updates: two weekly deployment windows
Planned CheckersArena updates will use Tuesday 03:00–04:00 and Thursday 04:00–05:00 in the Europe/Warsaw time zone.
Our two provisional windows for planned updates are Tuesday 03:00–04:00 and Thursday 04:00–05:00, Europe/Warsaw. These local times follow Poland’s daylight-saving and standard-time changes.
Most preparation and testing happens before the window. A short maintenance page may appear while a release is switched. The window also reserves time to verify the new release and, if necessary, restore the previous one.
These windows do not cancel tournaments. We check active games before each update and postpone a deployment if the change could disrupt them.
Change lists and postponement notices will be published in the blog under “Service updates”: /blog/en. Urgent fixes for serious bugs or security issues may be deployed outside the schedule; their details will also appear in the blog.
This schedule is provisional. We will review traffic and tournament activity and announce any changes in the same place.
