This is the opposite of my recollection, actually. I distinctly remember having conversations about Github struggling to scale well before MS was involved, and people claiming that MS had somehow saved Github because it had stabilized and begun adding features again.

Do you have any sources to back your claim up? At what point did Github fail to scale their search endpoints?
