HTTP response times all over the place

Here are a couple examples from Chrome and Firefox.

I’m located in Wichita, KS and connected to dfw.

Chrome


Firefox

Those numbers do look really suspicious, I’m looking at some things internally.

What kind of latencies do you see with apps like https://debug.fly.dev and https://the-mist4.fly.dev ?

(Also, can you confirm debug.fly.dev shows ‘fly-region: dfw’?)

debug.fly.dev shows Fly-Region: chi even though dfw is substantially closer to my geographical location.

Hello there,

We don’t have an update for you yet, but we’re still investigating this.

Thanks for the response. Let me know if y’all need any more information from me.

Was there an update on this? Latency is one of the big factors of me moving to Fly.io, so any conclusions to random spikes would be appreciated.

I never received an update to this but 99.something % of the time, my response times are less than 100ms. I do still have random latency spikes to around 4.5 seconds and I can’t correlate that to any requests from my API, so I guess the problem is mostly mitigated.

Very much appreciate the timely response! I guess it’s mostly mitigated… part of the reason I was developing in Go was avoid p99 latency. But I guess I forgot about the deployment impact that as well :slight_smile:
