I agree, AWS (and Amazon Alexa + Ring) seem to be skirting and/or choosing active silence on that "Lambda" outage that took out us-east-1. Alexa had at the very least two full scale outages this year, and Ring was successfully hacked as well.
Amazon's response: "looks like a Lambda... more later" then nothing, nothing, and "it must be a 3rd party skill."
AWS health page: GREEN.
AWS Post-event summaries: non-existent after 2021.
This is quite troubling when you consider what AWS holds in its coffers, along with the number of customers AWS currently has. No transparency, not even strategic transparency, is a definite red flag.

I vividly remember when AWS Fault Injection Simulator first launched, posting a meme in the #aws-memes slack channel posting a drake meme with the first panel being "Using AWS Fault Injection Simulator", and the second "Deploying in us-east-1".
That's like buying a backup generator from a guy that wants to meet you in the Walmart parking lot.
