Hi Craigski,
Sorry to hear that.
I am unsure why Gradwell are blaming BT as I would be very surprised if this was a BT issue.
Also Gradwell do appear to be upgrading their hosting servers over the weekend.
"Overview
Our engineers are carrying out an essential upgrade of our core routing infrastructure."
I am not saying this is the cause but it does point to the fact that they are aware of routing issues and are will be carrying out work on this (this is in relation to their hosting services as well).
I did test this on our side on a BT connection and our internal Network.
Bt connection no website - Ip address shown on trace - 195.74.61.93
Network (working website) - Ip address shown on trace - 195.74.61.93
Now if these IP addresses were different this would potentially point towards a routing issue on our side, also both traces showed the same hops etc.
The only thing that I can think of is that Gradwell are possibly blocking a certain range of IP addresses.
I have asked a colleauge to see if there are any more reports.
Thanks,
