alt Hacker NewsIt's basically what leads to extended downtime almost every time. There are just some things in the stack that are still single points of failure, and when they fail it's a mess.

a circular dependency and a single point of failure are not the same thing. If I have a single point of failure and it is down, I fix that and things work again. If I have circular dependency, there is no obvious way to fix anything that is broken any longer.
Yes, I concur.
Sometimes the circular dependencies get almost cartoonishly silly.
Like, "One of the two guys who has the physical keys to the server cage in us-east-1 is on vacation. The other one can't get into his apartment because his smart lock runs into the AWS cloud. So he hires a locksmith, but the locksmith takes an extra two hours to do the job because his reference documents for this model of lock live on an S3 bucket."
I made that example up, but only barely.
