Which is all fine and dandy - then use a service that provides the required SLA and pay the price (github business or enterprise, have someone host gitlab for you with the required SLA, ...) or store your data redundantly in gitlab and github at the same time (git can do that) and factor the overhead into the bill. I'm not saying a good uptime is impossible - it's just something that will cost (a lot of) money. Bill accordingly. All the while keep in mind that the SLA of the source code hosting should not have any impact on the uptime of the service itself. Clients - especially larger ones - as a matter of fact do understand that the SLA on issue tracking, code hosting etc. can differ from the SLA on the app.
