You can check the status of github in real-time, incl. historical data on system performance, follow incidents or scheduled maintenance by going to: https://www.githubstatus.com/.
Similarly to check the status of Azure DevOps you can use: https://status.dev.azure.com/.
Both status pages also has an RSS feed. In my next article/tutorial I will show how to create an Azure Logic App that will notify you when any of the services become degraded.
