I won’t say which ones, but BT have taken it upon themselves to prevent access to some web sites urls.
There is a way round this using a proxy service called Tor, I’ll show how for Xubuntu. Tor also offers benefits of more anonymised browsing on the interweb.
At long last super fast broadband has come to our location, so I bit the bullet and went with BT, following a long relationship with Zen, who did offer the service but were just too damned expensive.
The engineer from Openreach appeared on Friday and within the hour I was connected up. The online calculator offered 36 down and 6 up, but immediate experience showed somewhere between 12 & 22 down and 3up, still a vast improvement on 1 down and 0.25 up 😉 Was able to do in minutes what previously took hours. I hadn’t expected great things in terms of speed. Given I was paying the same price for 1mb any improvement was worth the switch.
