Re: Microsoft 365?
We had a regional outage on authentication in Azure which borked up not just the SharePoint Online and Dynamics/Office365 access but also our on-prem stuff as that uses AAD in the authentication stage as well via ADFS. This was not reported on the Health page in Office 365 and were it not for an embedded MS employee that alerted us we'd have been none the wiser. This seems almost like a tactic of MS's to avoid people noticing what the real uptime is. If it only reports system-wide outages, that's not really being transparent is it?
