Not much loss there, it hasn't been updated since about 1998, though it was the first site to provide caps of all the ITV idents from the Generic look of 1989.
I'm surprised the Webmaster kept the site up and running and online until 2006.
Gatecrashing this thread slightly, I've notice that Border TV Area and The Grampian Television Studios are offline too. Bit of sudden cull of Pres TV sites going on at the moment.
Maybe they are updating with the common new ITV look.
I doubt it, that website has been around for a long while, bearly active, and they decided to close it, not much lose though, because most major TV Pres websites have videos of the 1989 generic look.
