Hi Philipp John

Thanks for reaching out to Microsoft Q&A.

Here are some insights and steps you can take to address the problem:

Azure periodically performs maintenance on services, which can lead to temporary unavailability. Ensure you've checked for any notifications regarding scheduled maintenance for your server. You can manage and view maintenance schedules as described in Scheduled maintenance in Azure Database for PostgreSQL - Flexible Server.

Navigate to the "Resource Health" section of your PostgreSQL server in the Azure Portal. This section provides insights into the current health status and any detected issues that might be affecting your server's performance or availability.

Access the server logs to identify any errors or anomalies that occurred prior to or during the service disruption. Detailed logging can offer clues about potential causes and guide troubleshooting efforts.

Ensure that regular backups are configured and consider geo-redundant storage options. This practice safeguards your data and allows for restoration in different regions if necessary.

Utilize Azure's monitoring tools to set up alerts for metrics such as CPU usage, memory consumption, and connection failures. Proactive monitoring can help detect and address issues before they escalate. Refer to Monitor metrics on Azure Database for PostgreSQL – Flexible Server for guidance.

Kindly go through below document on the actions which you can take due to service health issue

The current undefined status and UnknownReason suggest that this is an early-stage incident still under investigation

It's almost a year later and we are running into the same issue.

What's the point of this Q&A site anyway? People post their problem and there's no solution in months? Is this a self-help group?

Hi @ Philipp John

Microsoft has identified an issue impacting your Azure Database for PostgreSQL – Flexible Server. The current undefined status and UnknownReason suggest that this is an early-stage incident still under investigation. As a result, service availability may be temporarily affected for Flexible Server instances in the impacted region.

Here are some checks you can perform, along with possible reasons for the issue:

Check Azure Service Health: Go to the Azure Status Page and filter by Switzerland North Or, check the Azure Service Health blade in the Azure Portal for personalized impact and updates.
Set Up Alerts: Go to Resource health under Help and create a Resource Health alert to notify you when the issue is resolved or escalated.

enter image description here

Azure Database for PostgreSQL Flexible Server goes through regular maintenance to ensure your database stays secure, stable, and up to date. During these maintenance windows, the server receives updates, patches, and new features. While some downtime may occur, the duration typically depends on how busy the server is with transactions at the time.
Failover Strategy: If your Server has geo-redundancy or backups in another region, consider failing over to a healthy region or restoring backups.

Hi @PratikLad

I seem to be experiencing a similar issue

it has been repeating over the weekend

I've checked Azure Status Page in my region and there is currently no maintenance taking place.

Hi @Kinson Li The issue can be caused by excessive memory consumption. When too many connections were made to the database, it overwhelmed a service responsible for managing connections not the database server itself. To resolve this, upgrade the memory accordingly and limit the number of connections from the application server.

Hi @PratikLad Thanks for the feedback, we are going to load a backup version of our DB and monitor memory consumptions.

Hi @PratikLad I grabs a screenshot of the memory usage before the service stopped

Nothing of note happened before it happened
