Everytime I visit a site hosted on CloudFlare, I get error messages like then one below. I encounter this a few times daily. Thus, I'm unable to view the site unless I go through a proxy site. Going to the CloudFlare website itself produces same error. I contacted CloudFlare support but they weren't helpful.

I currently don't use their service. I've pored over my network preferences, etc. but nothing helped. Would appreciate any input to help me resolve this.


DNS Points to Prohibited IP

You've requested a page on a website (www.cloudflare.com) that is on the CloudFlare network. Unfortunately, it is resolving to an IP address that is creating a conflict within CloudFlare's system. If you are the owner of this website, you should login to CloudFlare and change the DNS A records for www.cloudflare.com to resolve to a different IP address.

Timestamp: 1364584837

What is your country? Who is your ISP? What shows in your HTTP headers when you visit an online IP address tool (e.g. mine)? –  Michael Hampton Nov 26 '13 at 0:14

Hey this could be a remnant of the Great CyberBunker vs CloudFare + Spamhaus attack of this week- March 2013.

OK Cyberbunker or somebody else, launched a DDoS attack on Spamhaus this week. CloudFare is a contractor to Spamhouse, doing denial-of-service packet filtering and re-direction. So, CloudFare also became a target. At some point Cyberbunker also was targeted, and as of my reading today, the authors of the attacks are unclear.

The error you got sounds like this sort of attack. If anyone knows better, I'd be interested.

The Answer is: DDoS attack prevented you from getting to the sites. If you try again the error will go away. I think the attacks are tapering off by now.

Thanks for your post John. It's not really an answer isn't? –  Jacob Jan Tuinstra Mar 29 '13 at 21:58
