Here's curious. BT customers, don't try this at home (because your UID/security credentials will leak to an American server operated by Phorm).
Add this line to your host file (either /etc/hosts on linux, or c:\windows\system32\drivers\etc\hosts. on Windows).
207.44.186.90
www.webwise.bt.com
This causes
www.webwise.bt.com to resolve to its old US of A address. Now visit
www.webwise.bt.com in your browser... tada! Its still there!
Hey welcome to dubyadubyadubya.webwise.bt.com, have a nice day now.
So while they changed the DNS, they didn't actually take the site down.
Anyway, sorry for that irrelevant interlude. I'm off to compose my letter to Ms Reding.
