I just started getting a problem where image files will randomly take a really really long time to load. I’ll load a page and it will load instantly, then I’ll ctrl+F5 a couple times and it will be fine, but then randomly one of the images will take minutes for TTFB. When it finally starts loading it takes milliseconds to get the file. The waterfall looks like this:
I’m fairly sure this is a cloudflare issue because I’m getting the same problem on two different servers that are in two physically different data centers running two different versions of CentOS. Both are on 1gbps ports and under minimal load.
I don’t want to turn off cloudflare for testing because I’ve had some bad DDoS experiences and I don’t want to risk exposing my origin IP.
