I just tried pinging twitter with this tool, the turkey server seems to work: http://cloudmonitor.ca.com/en/ping.php?vtt=1395356295&varghost=twitter.com&vhost=_&vaction=ping&ping=start http://cloudmonitor.ca.com/en/ping.php?vtt=1395356295&vargho... but china, egypt, and interestingly panama don't. I'd love to report on this but it's hard to prove this kind of thing. any ideas? (i'm also contacting twitter) edit: here's my story - http://www.nbcnews.com/tech/social-media/twitter-blocked-nationwide-turkey-reports-n58276 http://www.nbcnews.com/tech/social-media/twitter-blocked-nat... please let me know if you see anything wrong. (we're aware of the turkish character issues...sigh)

Hi, The method for blocking websites in Turkey is through ISP's DNS servers. So when you don't use a Turkish ISP DNS server you are all good with most of the blocked sites. Some websites, especially popular porn sites are blocked through the IP. In such cases you need a VPN or proxy. The tool you are using to check Twitter servers probably don't use a Turkish DNS server. If you don't believe, check the website status from the Informational Technology and Communication presidency of Turkey website: http://eekg.tib.gov.tr/ http://eekg.tib.gov.tr/ The court orders are displayed both in English and Turkish.

    You are welcome. If you have any questions feel free to ask, you can reach me by twitter too: @mrtksn this is how the DNS Look-up for twitter looks like at the moment: http://i.imgur.com/yKmmDYc.jpg http://i.imgur.com/yKmmDYc.jpg I used TTNET's DNS server for this. It's the biggest ISP in the country.

It is a DNS based block. If that server uses a custom dns or has different caching rules etc, it would not be affected from the block.
