No AWS region is in a single building, they aren't amateurs like Azure. Each region is at least 3 AZs, which is at least one physical DC.

Touché. Still I'd rate the overall reliability of AWS higher than Azure; and even if that weren't the case, security issues make Azure look like a very poor choice.
