I don't know anything about githubs codebase, but as a user, their software has many obvious deficiencies. The most glaring being performance. Oh my God, github performs like absolute shit on large repos and big diffs.
Performance issues always scare me. A lot of the time it's indicative of fragile systems. Like with a lot of banking software - the performance is often bad because the software relies on 10 APIs to perform simple tasks.
I doubt this is the case with GitHub, but it still makes you wonder about their code and processes. Especially when it's been a problem for many years, with virtually no improvement.
