Freemium model
Github was around before anyone was talking about "the cloud". They were (and are) a free git hosting service, where you can pay for ugraded services.
It is senseless to complain about availability on the free side. Pay for it or run your own. (A previous employer of mine was running private GitHub--they sell that.) And shame on you and fie on your business if you have paying customers and are relying on a free service in order to satisfy your contractual obligations.
If their paying customers are having a problem, then this is a much more serious matter. The reports suggest that they are using some bs "eventually consistent" model of data resilience. Best review those contracts.
