As you can see the server goes down arbitarily and takes much time to come back online.
Note: My repl gets plenty of traffic so this is not a traffic issue.
I have even tried always on repl and boosting but same performance. Then moved to another hosting.
Can anyone tell me why this is happening and how to solved this?
It seems fine. You can boost though I don’t think that’s needed. Deployments are coming into beta soon where it will have 100% uptime. You can email soren@replit.com requesting to be part of the beta in a few weeks.
