It is very weird, here is whats happening.
https works on some godaddy pages but not the member area
other https websites work
godaddy member area works if I use squid (proxy through my own server)
so its possible the route from the godaddy ssl server to ntl is messed up
https://registrar.godaddy.com is ok but
https://www.godaddy.com isnt however
www.godaddy.com is fine.
