Every year or so I check back in to see if Cognito has gotten any better. I hasn't. I'd love to use it, but some very basic things are just not done correctly. Yan Cui has a nice writeup on Cognito [0] that touches on some of its shortcomings.

My blood pressure is still coming back down from AWS having an all-day outage during a holiday week last year, because Kinesis had an issue and it turns out their entire infrastructure depends on that.

Agreed! just got done replacing Cognito across the board with Auth0, glad we hadn't pushed it to prod yet.
