Whilst that's crazy, github hasn't migrated to azure yet, so it's probably not exclusively an azure problem and we've seen the same problems with amazon too ( and several other large orgs ).
Github thanksfully not, but GH actions are running entirely on Azure. They've setup actions as a testbed for Azure afterall.
