Check for upcoming maintenance for Azure IaaS VMs

Q. How can I check for upcoming maintenance for my Azure IaaS VM?

A. From within the Azure IaaS VM view http://169.254.169.254/metadata/scheduledevents?api-version=2017-03-01 which will download a JSON file which will outline any upcoming maintenance. You could also fetch this using the curl tool, for example:

curl -H Metadata:true http://169.254.169.254/metadata/scheduledevents?api-version=2017-03-01
