Rails is (apparently still) a popular target for haters, but for projects at Github's scale it's rarely a code logic/framework-level blunder that's taking the service down. It's generally a cascade of failures in things like multiple database systems, auto-scaling, dns/caching, etc.
There are projects bigger than GitHub that do all of these things and still doesn't fail as much as GitHub. Honestly, both of us speculating. You can't say for sure if it's not Rails and I can't say if it's not anything else.

This is just guessing. You can't honestly tell what is causing the issue.
Not guessing, postmortems are regularly posted on this site and elsewhere. These kinds of failures are generally not someone using some "magic" (or whatever other pejorative term) feature of a framework.
