Where and how are you getting that reliability data? And what is it for? All services? A region? Everything averaged out? I know companies embarking on multi million dollar projects to add a backup identity provider to EntraID because it's that unreliable and it costs them money every time it's not working.

Azure was the cloud that had all global auth rely on a single DC in Texas (we learned when cooling failed there), and didn't have availability zones in most regions until not that long ago. They've also had a number of trivial cross tenant exploits. No, two us-east-1 outages that had minal global impact isn't comparable, we're talking about all auth for all of Azure using a single DC, not a region of 5 DCs having the control plane for global AWS services.

Neither security nor reliability are a priority. It's by far the worst big cloud provider, and it's not even remotely close.
