Application up time is flakey, but what was worse were fly deploys failing for no clear reason. Sometimes layers would just hang and eventually fail for no particular reason; I'd run the same command an hour or two later without any changes and it would just work as expected.
I'd love to make a monitoring service to deploy a basic app (i.e. run the fly deploy command) every 5 minutes and see how often those deploys fail or hang. I'd guess ~5% inexplicably fail, which is frustrating unless you've got a lot of spare time.
Their support still leaves a lot to be desired even as someone that pays for it but the ease of running and deploying a distributed front end keeps bringing me back.
Always good to monitor your dependencies if you have the time. Then when someone complains about an issue in your service, you can check your monitoring to see if your upstream services are broken. If they are, at least you know where to start debugging.
Looks like it lasted 16 minutes for them.
The entire API was also unusable, not just deployments.
