War Thunder servers may become unavailable on September 16, 2026, from 08:00 GMT. In an official announcement published on September 15, Gaijin links the potential interruption to the release of the major Sky Odyssey update. The notice does not confirm that downtime will definitely occur, but 08:00 GMT is the time players should watch. Read the official announcement on Steam.
What changes for players on September 16
Anyone planning a session around 08:00 GMT should allow for War Thunder access to become unavailable. The announcement gives a possible start time, but it does not provide an end time, so there is no reliable maintenance duration or precise return-to-service estimate yet.
the official Steam post The stated reason is the release of Sky Odyssey. Gaijin says the full announcement for the major update and the complete major changelog will be published once the update has been released and is ready to play. The current notice therefore establishes when access may be affected, while leaving the update’s detailed contents for a later publication.
The announcement does not yet list the fixes, features or other changes included in Sky Odyssey. It also provides no platform list, region, price or edition information. Those omissions do not change the announced time to monitor, but they mean this notice is not a complete deployment schedule.
What to do while the update downloads
If you intend to play on September 16, avoid scheduling an important session around 08:00 GMT and check the official communication when the update becomes available. Gaijin also directs players to the dev blogs for information about the upcoming content during the download.
JEU.VIDEO The practical takeaway is limited but clear: Sky Odyssey may interrupt access from 08:00 GMT, while the duration and exact update contents remain unknown. The full changelog, due when the update is ready to play, will provide the next confirmed details.
