Azure App Service release hangs and then fails

We got a hazardous deployment on Azure: in every 4-5th release the pipeline timed out after 60 minutes of waiting for Azure. First we suspected Azure services, as the script was hanging on their API call, but there was no outage report. Tried to investigate other deployments when this one failed, but every other worked just fine. Searching Microsoft’s wiki gave the answer:

A release hangs for a long time and then fails, a “503 service unavailable” error occurs, or the deployment history in the deployment logs fails to update

It turned out that the App Service Plan was hosting multiple, small services which took most of the resources, making the deployment hazardous.

Increasing the App Service Plan’s tier solved our issue.

Azure App Service still logging when stopped

Leave a reply

Encountered a mysterious issue these days: stopped the App Service on Azure, but the application was still logging, like nothing happened. Waiting couple of minutes, then half an hour, but logs were still coming.

Checked the generated url and the site responded as it should:

Turned out, that the App Service was hosting WebJobs, not a classic web app and the default “Stop” doesn’t apply to them. To turn off WebJobs, one need to navigate to WebJobs blade of the App Service.
