How many services have meaningful SLAs for extreme downtime?

Github and (parts of) AWS will give you a small discount at 0.1% downtime, a bigger discount at 1% downtime, and AWS will refund the whole month for 5% downtime. But beyond that they don't care. If a particular customer gets no service at all then their entire $0 gets refunded and that's it.

That was just a feature of the product to be helpful. Not a core function at all.
