"AWS reveals it broke itself by exceeding OS thread limits"

https://www.theregister.com/2020/11/30/aws_outage_explanation/

Especially:
"The TIFU-like post also outlines why Amazon's dashboards offered only scanty info about the incident – because they, too, depend on a service that depends on Kinesis."

Perhaps there is something we should specify in ANIMA to prevent the ANIMA infrastructure falling into this sort of trap: when there is a system-wide issue (such as hitting an O/S resource limit everywhere at the same time) it also prevents the autonomic mechanisms from working.
