Huge HTTP latency increases

[matsea]

I’m currently expecting tons of HTTP timeouts and latency increases for calls I’m making from my app to the outside world. Any known issues going on?

Hi,

To debug, Fly may need some more details. Such as the region the app is running in, and perhaps the app name (though you may not want to reveal that in public). Since there are occasional issues with host machines and that may help narrow it down e.g

Fly Machine becoming unresponsive and then stopping without explanation

Ok, turns out the underlying host became heavily loaded which resulted in a lot of i/o and network slowness. We’ve been working to apply better some limits on our hosts which should prevent this issue again but could also result in being unable to schedule a machine of the size you’re requesting (depending on the region).
