Blocked sites, all web browsers, Linux and Windows


This last week or two I've encountered many Error 404s, page not accessible. As the problem seemed to occur with just a few domains, I tried accessing the home page of one, torrentz.eu, and instead of their home page, got the following message

Blocked Site

The website you have tried to access has been blocked by an automated filtering engine. In order to preserve a "family-friendly" atmosphere, we block adult related websites as well as peer-2-peer, illegal file downloads, and file-sharing websites.

Even though we do our best to ensure that appropriate sites are not blocked, content filtering is not an exact science and we sometimes block sites that fit within the family friendly guidelines. If you believe this site was blocked in error, please use the form below to submit your unblock request. Please include your email address in the comments section if you would like to be contacted.

We will review your request and take appropriate action in a timely manner. We apologize for any sites blocked in error and will work urgently to correct them.

Thank you for your assistance and cooperation.

To my knowledge I've not installed any such software as would do this, and certainly not on both OSes. Does anyone know what this is about, or where these anonymous censors come from?

tcptraceroute to one of the offending sites on TCP/80 and see where the trace peters out? Or tcpdump TCP/UDP 53 and TCP/80, send a request (use something easy like cURL), then check the IP address the response comes from? It's likely your ISP not an "anonymous censor".

Thanks for this info. slackware does not include either of these so I must install them first.

That's odd you can reach it but I can't, http://www.downforeveryoneorjustme.com/torrentz.eu gives me the result

It's not just you! http://torrentz.eu looks down from here.

Check another site?
Where are you located? This has me wondering now if our noble and exalted leaders have finally declared us to be the world's last best hope for repression and censorship.

Just checked and the site definitely is not down BTW. Another way to check could to send HEAD or maybe even TRACE instead of a GET request and see if they (or the end point) doesn't block that too? Else try HTTPS? (Doesn't work for torrentz.eu tho.) *Do note running diagnostics is one thing but anything beyond that may come close to circumventing access restrictions which isn't a LQ topic. Just be careful what you ask and how you ask for it.

Hang on, I'm still working on the first suggestion. I got
Code:
~ $ traceroute -w2 -q1 -f 5 www.torrentz.eu  
traceroute to www.torrentz.eu (205.139.50.143), 30 hops max, 60 byte packets
 5  sea-brdr-02.inet.qwest.net (67.14.41.18)  53.470 ms
 6  208.173.49.93 (208.173.49.93)  56.417 ms
 7  cr2-te-0-5-1-0.sel.savvis.net (204.70.224.49)  64.669 ms
 8  cr1-te-0-2-0-3.ald.savvis.net (206.28.96.117)  128.500 ms
 9  hr1-te-1-0-0.atlantaat1.savvis.net (204.70.197.157)  125.866 ms
10  *
11  *
12  *
13  *
14  *
But how do I interpret this? Wait, I think I realize what the problem is. I'm away from home and using an internet cafe wifi connection. I assume their system has the filter on it. Thanks for your help.

We hear a lot about China blocking sites. In the 'Land of the Free' they do that too?

We're free to obey here, just like everywhere else.

But in this case, it's not a government that's blocking web access. It's a private company that's providing free access, but just wants to limit what you can do with the gift they give you.

You can hardly blame them, here in the land of lawyers. The DMCA got a bunch of kids arrested for downloading music, so it's likely that shopkeepers would fear they would be charged as facilitators and accomplices if you do something against a law (regardless of how corrupt).
