Hi guys,

I have three static web applications (DEV, UAT and PROD). They were working good till yesterday.
Today I am encountering a problem accessing these applications.

I get a 503 error code when I open each of these three domains. At the same time.

Today from 8am to 12 we had this problem and none of the static web apps worked.
From 12 to 4 pm everything worked fine, without any problems.
And from 4pm all static web apps at once stopped working and I get a 503.
There were no changes on my side in the infrastructure today.
The site loads.... loads... and nothing happens, sometimes after 5 minutes it opens.

Any ideas?

    A 503 error code in an Azure Static Web App indicates that the server is temporarily unavailable or overloaded and cannot process the request at the moment. This error is typically caused by one of the following reasons:

    1. High Traffic: If your website is receiving a large number of requests simultaneously, the server may not be able to handle the load and returns a 503 error.
    2. Deployment Issue: If there is a deployment issue, such as an incorrect configuration, missing files or dependencies, or an error in the woriosbuild process, the server may not be able to serve the website and returns a 503 error.
    3. Server Maintenance: Sometimes, the server may be undergoing maintenance or updates, and as a result, the website may not be available temporarily.

    To troubleshoot the issue, you can try the following steps:

    1. Check the Azure portal to ensure that your static web app is running and deployed correctly. If there is a deployment issue, you will need to fix the issue and redeploy the app.
    2. Check the logs to see if there are any errors or warnings that might be causing the issue.
    3. Verify that the routing rules are configured correctly and that the website is accessible from the internet.
    4. Check the server's resource utilization and consider scaling up your app or adding more resources to handle the load.
    5. Wait a few minutes and try again, as the issue may be temporary and could resolve on its own.

    If the issue persists, you may need to contact Azure support for further assistance.
