Reinvent VMS-style clustering on BSD/Linux boxes or just buy some VMS servers. They measured uptime in years to decades for tech that started in the 80's. There should be several, modern solutions like that given companies were developing them a long time ago when I first looked into such things. I just haven't surveyed to see what exists, is reliable, and is affordable. They could also have a base version of the site that's read-only for source or binaries to allow customers access to the data to fall back to whenever problems happen in more complex functions. Keep it running in some form while they fix things. They might also similarly sell Git appliances w/ high-availability that themselves plug into multiple colo's or cloud providers mirroring changes in the repo to the Github site. Just a wild idea as I have no idea if that's marketable.
