I talked with @kurt via DM on Twitter about this. I’m testing a project on Fly again and seeing the problem again.
It seems that every couple of requests there is an SSL latency of a second or more. I thought it may be a cache problem since it seems to happen after a couple of minutes without any requests to the app.
We are troubleshooting some load balancer load issues that are causing occasional latency spikes for the last few hours. If you’re seeing this now, that’s why.
@pier if you were seeing TLS (and even ttfb) latency spikes for the last several hours, it was likely a result of our load balancer issues. If you see them again we can see what’s happening.
