I there, I use Cloudflare for some of my servers. I tried using the cache system but while it works, it also adds more time to the load of the page (TTFB *) so it didn’t work for me at least on most websites. But, I still use the DNS service which is available to use without cache. So I use it mainly for the DNS and only a few pages use the cache. Nothing wrong here.
(\) CloudFlare says that the TTFB delay is not a big issue. I think the opposite.*
However, recently I found the next problems:
Cloudflare affects somehow the content of some pages even when you are not caching it. How, and why? I don’t know but Google Bots shows me some nonexistent links that were generated by CloudFlare.
And now, somebody is using the IP of Cloudflare to probe one of my servers.
The IP is owned by CloudFlare https://www.cloudflare.com/ips-v4
And my website does not use WordPress in any way and there is no file (or folded) with such a name. Also, there is no content or link to that file. I double-checked that.
So, what is going on with CloudFlare?
I don’t think CloudFlare is trying to hack my server and maybe somebody is using CloudFlare as some kind of proxy. But, since I don’t really know what is going on, then that IP of CloudFlare was banned from my system.
In any case, I think it is time to move out of CloudFlare.
Update: List of IPS banned so far.
