Looks like the core problem today was a DNS zone delegation issue during a migration off of legacy DNS servers. I'm not sure how this type of issue can easily be segmented by region due to the way the DNS service is designed and fundamentally zone replication works.

Yeah, DNS is pretty much an unavoidable single point of failure. Gotta do the best you can to keep global touches to it as light as possible.

It looks like the majority of their outages are listed as configuration changes as being the cause. You’d think they’d have an “RCA” at some point to address making configuration changes safer.
