Sorry for the offtopic comment, but it's bizarre to me that Google is hosting their book on Github with a github.io domain. Their previous two SRE books are hosted at https://sre.google on Google-owned IPs.[0]
What was that decision process? "We're Google, and we're literally writing a book about how good we are at hosting services. But hosting some static HTML files that are almost entirely text? That's a tough one. We'd better outsource that to one of our competitors."
I think one is a portal for GitHub developers, while the other is a public polished site. I reminisced the early Google forthright attitude that made life so simple and human.
sre.google links to this book, but it links to github.io. The other two books linked on sre.google point to within the sre.google domain, so this is the odd one out.
