Some load balancers may be having issues but I have multiple busy workloads showing no issues all morning. One big challenge can be that some people reporting multi-AZ issues are shifting traffic and competing with everyone else, while workloads which were already running in the other AZs were fine. It can be really hard to accurately tell how much the problems you’re seeing generalize to everyone else.

I do agree that the end of this year has been a very bad period for AWS. I wonder whether there’s a connection to the pandemic conditions and the current job market – it feels like a lot of teams are running without much slack capacity, which could lead to both mistakes and longer recovery times.
