Title says it all. Some IAD apps are just hanging indefinitely. I see an ongoing issue in the status page, but that seems to be for a BOM issue affecting India / Europe? And the last update there is from many days ago.
Ha - and just like that it’s all better 
I have right now, I can’t figure this out. Same error, unrelated to me since I am in IAD and users in US. I have few apps in IAD and only one of them is in continuous cycle of being down. I have cloudflare on top and min_machines_running = 0 (I had same issue with another machine and I fixed it for good by always running 1 machine). Cloudflare keeps showing me the 502 error that it can’t reach the host, the Fly logs say it’s trying to start machine and nothing else happens. Used to be fine months ago. The only thing that works (temporarily) is re deploy. CF cache purge doesn’t help.
Not sure if fly.io discourages min_machines_running = 0 now?
Yeah same! Things are down yet again - IAD as well. But only on SOME apps. I’ve even destroyed and re-created the machines for the affected app, but no change.
I have min_machines_running = 1 so I don’t think that’s it
Can you share your app’s name? Feel free to email me at <username>@fly.io if you don’t want to share it on the forum.
@pavel Gladly - app’s name is

It responds, but extremely slowly.
Request sent to machine (7819e72b910758):
Sep 15, 2025 @ 14:40:02.368756000 edge -> backend: Request { method: GET ... }
Response received:
Sep 15, 2025 @ 14:40:49.148486000 edge <- backend: Response { status: 200 ... }
Looking at the machine metrics, it’s doing a lot of I/O while serving the request (around 2k reads/sec) and is consuming 100% CPU (so it gets immediately throttled because it’s a shared-1x machine).
So it doesn’t look like a network problem to me.
Could you check from inside the machine what’s consuming so much CPU and doing so much I/O?

Interesting. Thanks a ton!
@pavel any chance you could point me in the directions of the docs that (I assume) show you how to ssh into a machine?
Thank you!!!
It’s just flyctl ssh console. You can also pass –machine <id> to connection to a specific machine:
