If they are using your data, you're still paying just not in cash.
As a former reliability engineer, I'm trying hard to remember back when we had multiple months in a row never reaching 100% uptime, and I can't. Yes, we've seen runs of painful months, but also runs of easy months without down time.
But let's talk root cause here, the cost of improving them here, is someone caring. This isn't simply a hard problem, it's a well understood hard problem that no one who makes decisions cares about. Which as a reliability engineer is an embarrassment. Uptime is one of those foundational aspects that you can build on top of. If you're not willing to invest in something as core as your code or service works. What are you even doing?
