Cool so its not only me.
The other week I fiddled with my internet settings and Pedro suggested that could be the cause of my problems. I also have found the same problem on another computer in my house on the same connection, so that ruled out settings to me.
Its frustrating when it looks as though the site is functioning normally for others.

Edit:
I use Internet Explorer but setup Firefox to see how it would go. With Firefox I cant even get the www.datsun1200.com front page. Display says " Connection timed out"

Suprisingly I have been able to get on and post 2 times today
