There's a reason I'm running full nightly mirrors of all of our private and public GitHub repositories...

The same applies to services. They can end tomorrow. Well, maybe not that fast, but how fast can you shift your business to an alternative without paying a terminal penalty?

We can't run without GitHub for more than a week, so we have to be able to get out in less. Same goes for AWS. Besides snapshots we run old-school backups to ensure we can recover on old-fashioned bare-metal if necessary.

Using those services, great. Letting our business depend on them? Never.
