My hotel uses OpenDNS to block access to the Tor website. Google Translate is also blocked. They are categorized as “Proxy/anonymizer”. This is one of the most annoying things about filtering. I just wanted to quickly translate some text from Russia to English and then read the Tor blog and ….
Yes, in order to block the Tor Blog, which uses HTTPS, they are MITM’ing SSL. (If you accept the bad certificate, the Tor Blog is blocked.) It doesn’t look like they are MITM’ing *all* SSL but just connections to selected IP addresses.
It’s funny, because I often recommend OpenDNS to people in order to avoid filtering, but OpenDNS also has a filtering service.
