I use Cloudflare for years, but from today all my sites respond very slow and often return “522 Timeout”.
This is an example of very simple static web site, which runs extremely slowly due to Cloudflare:
nakov . devbg . org
When I switch off the Cloudflare proxy, it runs normally.
Looks like an ingrastructure problem. In the last few months it worked normally.
I use a powerful VPS, which is loaded at less than 1%. No heavy teaffic and still sites proxied by Cloudflare load extremely slow (e.g. 20-30 seconds per simple request).
How can I investigate this?
