I’ve been using CF for a while now with no issues but the last few days my server has been pinned at 100% CPU and disk usage. Upon inspection I noticed that it was also doing 30mb/20mb on the network interface. I checked the access logs for my nginx server and its going absolutely crazy. I’m getting requests from lots of different IPs to sites like;
All 301 responses.
I noticed that most of these domains seem too use cloudflare for their dns. I’m getting in the region of around 150-200 requests a seconds which is much more than I expect.
I’m just a little bit stumped. I’ve also asked my server provider the same questions but I can’t seem to get to the bottom of it. It doesn’t seem malicious and looks like requests are just getting bounced off my server.
Any help is greatly appreciated. Thanks
