For anyone else needing their services, they are a perfectly reliable provider (most of the time). Would make sense to ensure a fail-over, though.
"But they're great", they cry, "why should I use anything else?"
Maybe, things are back faster than you could cover from any trivial issue.
All of my home's Ring cameras have been inaccessible this entire time. It's not that big of a deal for me because I planned for that eventuality, but a lot of people have not.
If you run a critical service (like Ring) and your infra is tied to CloudFlare - you're stuck! There is nothing at all you can do. That's freaking scary man. If I was working infra at Ring I'd much prefer to get paged and start fixing the problem. There are very few problems that can't be fixed in 15 minutes if you plan well for failover...
