At KickoffLabs we used them to handle a bunch of routing on behalf of our hosted customers.
The timing was less than ideal for sure.
However they arranged a good support system with the folks at Fly.io. We’ve already transitioned new customers to it and they are helping to migrate existing sites and certs next week.
I think it’s a risk you just have to take, but we learned a lesson that for things that are dependancies for your business it’s good to have a couple of alternatives lined up or working side by side. :)
