Security updates will be applied to the shared Central Oracle database (central-oracle-11) and five Central PostgreSQL clusters (central-postgres03, 06, 08, and central-postgres11 and 02 in the EU) on Sunday 25 October 2026, between 06:00 and 11:00 UTC (01:00–06:00 US Central / 06:00–11:00 UK).
The clusters are patched one at a time. Restarts take about 4–5 minutes for central-postgres03 and 06, 10–20 minutes for central-postgres08, 11 and 02 (restarts plus an instance resize), and 35–45 minutes across several short restarts for central-oracle-11. Applications will reconnect automatically. No action is needed.
