While debatably unprofessional to blame your vendor, I found this read to be fascinating. I'm sure there are blog posts that detail how data centers work and fail but it's rare to get that cross over from a software engineering context. It puts into perspective what it takes for an average data center of this class to fail: power outage, generator failure, and then battery loss.
I'm ultimately glad this happened because it very effectively helps illustrate how we are assigning a centralized gatekeeper to the internet at the infrastructure level and why it's a bad thing.
