Security patches will be applied to four Central database clusters (sql08eu-std in the EU, aurora-5-b, central-postgres05 and aurora-1b) on Saturday 24 October 2026, between 16:00 and 21:00 UTC (11:00–16:00 US Central / 17:00–22:00 UK).
The clusters are patched one at a time. Each database will be unavailable for about 5 minutes while it restarts, up to about 15 minutes for aurora-5-b and 15–30 minutes for sql08eu-std. Applications will reconnect automatically. No action is needed.
