Looking for some help troubleshooting an issue with Fly.
One of my client sites is using Fly.io as a reverse proxy to offer whitelabel domains for a Heroku app. This week I began seeing 500ms slower request speeds through the reverse proxy than directly through the Heroku site.
I knew there would be some latency when using a reverse proxy, but I was thinking the latency would be much less. I’ve checked the stats on the Fly app, the Heroku app, everything and it all looks fine. The only thing that looks out of place is the
traceroute. Here is an example site if you want to check out the traceroute: https://it.justtakesonecall.com/
Here are two traceoutes. The first goes directly to the Heroku app. The second goes through the Fly.io proxy. The latter takes over a minute to complete.
