I've just seen Eriba Forum UK is back online.
I took a lot of effort to track down all parties (Fast Hosts, Scala Hosting Etc. and Montrose Securities) to point out that something was seriously wrong. I would do the same Eriba Folk.
No further information so far on what happened but it seems a totally unusual event and my pressure on the relevant parties seems to have resulted in some form of action to restore things.
I've contacted the main man for the site asking what happened and if/when I get a reply that is not private I will update here.
