Everything's tradeoffs, economies of scale for centralising- easy to blame the provider if a fuckup happens.
But when it goes down it stops everything; same issue with AWS, Azure's ADFS, Cloudflare, ad infinitum. Half the internet can go away at a moments notice or the provider can turn on you personally because an automated bot dislikes your username and decides to blacklist your company.
(is my bias showing?)
Anyway, Late September/Early October is rife with outages for as long as we've been running internet services.
People speculate that it's the influx of new sysadmins/programmers, but that's debated.
