Azure PostgreSQL Flexible Server restore fails with InternalServerError from both Portal and Azure CLI in North Europe

We are unable to restore our Azure Database for PostgreSQL Flexible Server.

Source server:

Verified source server details from CLI:

• earliestRestoreDate: 2026-04-01T19:45:13.942021+00:00
• publicNetworkAccess: Enabled
• backupRetentionDays: 7

Restore attempts that failed:

1. Point-in-time restore Restore time: 2026-04-07T13:00:00+00:00 Failed from both Portal and Azure CLI with: InternalServerError - An unexpected error occured while processing the request. Fast restore from full backup Backup used: 2026-04-06T20:08:51.199443+00:00 Failed from Azure CLI with: InternalServerError - An unexpected error occured while processing the request.

Additional context:

• We also saw a portal message indicating PostgreSQL upgrade was unavailable due to regional capacity constraints in North Europe.
• Because both PITR and fast restore fail, and because this happens from both Portal and CLI, this appears to be a backend Azure PostgreSQL Flexible Server restore issue rather than a portal/UI issue.

Please investigate and escalate to the Azure Database for PostgreSQL Flexible Server team, and confirm whether this is caused by a backend restore issue and/or North Europe regional capacity constraints.
