[CA] Cox blocking torrent sites...

I've tried to access a few torrent sites, namely CGPeers and Torrent Crazy and all I get is the white wall of death. How can I verify that cox is either blocking these sites or specifically if they are blocking me from accessing them? I'm in the San Diego, East County region where they service. Can I call them and ask them directly if they are blocking these sites or me specifically? Anyone have these issues?

torrent sites are always going up/down. try a different DNS provider, we might not have the updated DNS after the server was moved.(which they do very often)

Normally I would say this is the case. However, I'm able to access them on another network without issue.

Did you try alternative DNS servers?

I will try it tonight and get back to you. Alternate dns services like OpenDNS or Google DNS should do.

both sites are responding to me on Google DNS and Cox DNS.

Where are you located out of curiosity?

Okay, i tried opendns and google dns and I still can't access those sites. I can access them elsewhere, but not here. How do I go about to see if cox is blocking my ip specifically?

Highly unlikely and pretty much nearly impossible. When you check these sites "work" how are you doing it? Same computer connected to another ISP, or some other computer on another ISP? You may want to check the computers host file/table. I can't imagine malware would blackhole specific torrent sites, but that is the next most likely scenario if alternative DNS doesn't work.

Have you done the normal, ping, tracert, etc. diagnostics first?

Have you checked www.torrentfreak.com to see if there is any news about certain torrent sites that are down? (just a news site about torrenting).

Have you checked your own system? Make sure the firewall is properly configured. Your HOSTS file isn't messed up.

I really don't think Cox is doing IP level blocking of anything (in fact, I haven't heard of any domestic consumer facing ISPs that do any kind of IP level blocking of public addresses.)

I don't think they are doing DNS blocking of anything either, though they DO have flaky DNS servers (I remember one time they had an entire day where DNS servers were down due to a routing loop, and routing loops are usually a pretty easy thing to find and fix; shouldn't take a whole day.)

There are even times when I have tried to reach a subdomain which at certain times of the day, Cox's DNS servers can't resolve, whereas other DNS servers can. Interestingly, Level 3's DNS servers can't resolve them either, and Cox's DNS servers are sourced from Level 3 (anycast address of 4.2.2.1, guessing mine resides in Arizona, so it may be different elsewhere.)

What you might be running into is DNS poisoning. It's possible that your gateway device (router as most people call it, though it's actually multiple devices in one) has an internal DNS server that has a poisoned cache, or even a poisoned hosts file.

Or worse, it's possible that your client machine has a poisoned hosts file.

Maybe its not cox, maybe its the sites[common if you hit and run]

I was using my mobile to check if I had access to these sites through my wifi network. CGpeers and CGforums loads, but not Torrent Crazy through my mobile. So I'm gonna go look at my hosts file and see if they are there too.

I looked at my hosts file and nothing is in there relating to cgpeers.com or torrentcrazy.com. I can load cgpeers.com now due to hunting it being blocked by a malware program i have running, but i didn't know it was blocking it. However, torrentcrazy.com won't load even if I shut down all of my malware/AV apps. flushed dnscache. Not sure where to look at this point.

I do not think the problem is because of Cox. I am getting DNS resolution on the site and I can see traffic being passed back and forth in Wireshark.

The page never does load in a web browser - this is the response I get from a telnet session:

Not sure what you mean by that, but COX has it's own discrete DNS servers. L3 has anycasted DNS servers all over america in a few of their larger peering points/datacenters.

I have Cox in Orange County, CA and can't get to torrentcrazy.com either. But I also can't get to it through Clearwire. But downforeveryoneorjustme reports that it is up. CGPeers was down yesterday but I can get to it from Cox today.

I think we have ruled out that Cox is blocking torrent sites. Those are just flaky sites that go up and down on a whim.

No, that hasn't been ruled out since I can connect to torrentcrazy.com through my verizon 4g connection, I can connect to it from my work computer, I can connect to it through my at&t 4g connection and most other wireless connections outside of cox. As a matter of fact, I just did a brand new install of windows 7 on this computer that I'm typing on right now and I can't access it through cox either. There is nothing loaded on this machine except for internet explorer. At this point, I have to assume that cox is either blocking it or rerouting it into a black hole somewhere.

Or torrentcrazy.com is blocking Cox, some or all of their IP blocks. Meanwhile I'm seeing the exact same thing (page won't load) using Clearwire. I think it is on TC's end.

Not a DNS or routing issue.

Cox sources direct from one of the root servers?

That would certainly be interesting to note that TC might be blocking itself from these blocks of ip's. I wonder if it's intentional. Certainly interesting.
