This notification is for upcoming planned maintenance to your Azure Database for PostgreSQL instance(s) in East US. This is scheduled to occur between 22:00 UTC on 08 Feb 2023 (17:00 Eastern Standard Time on 08 Feb 2023) and 13:00 UTC on 09 Feb 2023 (08:00 Eastern Standard Time on 09 Feb 2023). During planned maintenance on your Azure Database for PostgreSQL instance(s), there can be database server restarts or failovers, which might lead to brief (60-120 seconds) unavailability of the database servers for end users. The entire planned maintenance event including each server restarts is carefully monitored by the engineering team. The server failovers time is dependent on database recovery time, which can cause the database to come online in minutes to hours if you have high transactional activity on the server at the time of failover. To avoid longer unavailability time, it is recommended to keep transactional workload light and defer long-running transactions like create index or data load to minimize disruptions to your application.
