GitHub was a heavy S3 user before MS took control. It may eventually move over to using their infrastructure more, maybe using it exclusively in the distant future, but there is no point rushing in such a massive systemic change. MS presumably learned something from the debacle that was moving HotMail's back-end from Solaris+Apache to Windows+IIS back in '97/'98!
