My company switched to a different provider for our action runners partly for reliability reasons. Despite that, jobs still aren't being dispatched.

Meaning your alternative provider is also facing massive outages?

I hear many complaints about github these days due to outages. I am genuinely curious if anyone has switched recently to a competitor for this and gets more uptime?

github action implements other providers by essentially a request to your runner. so if actions go down, the action supervising your different provider would likely not run so you're going to have an outage anyway
