I am using Cloudflare for the last couple of months and everything was working perfectly until last Friday when suddenly my website starting to open slowly. If to be accurate it takes around 8-20 sec on “Waiting for ----.com” and sometimes GTmetrix was giving server time out error, sometimes it was showing full load time is 9 sec and for the last few hours, it shows analysis error. This occurred after I tried to change the DNS nameserver back to the host’s server but when I couldn’t find any improvement, I changed it back to Cloudflare’s DNS nameserver.
Please could you please tell me what can be the issue… My hosting company is saying that server is working fine. One more important point is that I have one more site on the same server (which is not connected to Cloudflare) and that site is still working fine that’s why I am suspecting that the issue is from the side of Cloudflare…
Could you please help?
