I've got my most frequented sites as icons on desktop. Every so often, the VOD icon tells me the site is down, or offline for some other reason.
All I do is google VOD, go to the site, and copy the address into the link box of the icon.
It's only VOD that does this, out of 20 or so sites.
Took me a while to work it out, including posting up on here that VOD was down.
