Please note that we are about to change the forums name servers. This
may mean that you won't be able to access the forum for a while until your ISP updates their cached name server records.
In theory this should be no longer than about 5 minutes but we know that ISP's like BT sometimes have long refresh periods. In essence we have no control over the downtime for each individual as it's very much with their ISP to automatically update their records.
Basically we need to make the change as we are moving from two name servers to a Anycast system that gives us a presence on 27 servers spread around the world. It will basically give us some availablity advantages and a tad faster loading speed. We also need it in place for some other improvements we are making in the new year.
If the site dissappears for you just leave it a while and try again later - we'll be back

Cheers
