You need to either ensure you control the resources you depend on, or plan for outages. At my gig, we use GH Enterprise (on-prem) as well as some smaller plain-vanilla git repos (mainly for CM and other critical services). Any third-party code and all other dependencies live in an artifact manager or private mirror repos. Personally, I don't use any cloud provider to store my data. Cliche, but true: if you don't control the hardware, you don't control the data on it.
