If the motivation for moving off GitHub was "GH is down too much", it might be worth tracking how many 9's of uptime is lost in the self-hosted case.
Also, though GitHub's lack of reliability was part of the motivation to self-host, it was only a minor factor. The way they are trying to make Copilot a thing, at the cost of everything else, the way they handle US sanctions by blocking everybody from entire countries, and the way the web interface feels ever more heavyweight and sloppy were also factors.
Also, not to be an apologist, but I trust you realize that "the way they handle US sanctions by blocking everybody from entire countries" is how US companies are required by law to act. Not all do act that way, of course, but almost any that have enough overseas customers to matter do, because they have enough overseas customers to need to be aware of those laws.
