You can easily check which DNS servers have blocked the sites via nslookup :



EDIT : If swapping the DNS is not working for you on a TM service (Streamyx/Unifi), it might just be due to DNS caching. Close your browser + make sure you're on OpenDNS/GoogleDNS + run 'ipconfig /flushdns'. Then try pinging one of the blocked sites and you should see the IP address for the domain next to the domain name. If DNS name resolution fails, try setting a static IP mapping in your C:\Windows\System32\drivers\etc hosts file. Worst case scenario is they route blackhole the IP addresses for those websites, then you will need a HTTP/SOCKS/PHP proxy/SSH tunnel/VPN to reach them.

They have the firewalls in place to do HTTP header filtering on the Streamyx network (as we saw with the HTTP throttling last year). I think if they go full retard, we'll just compile a thread with every bypass method for each ISP + keep it updated

Resolving fine on TM DNS (202.188.0.133)
