I don't know if it is related because...
1. I'm on Blackberry
2. My bookmark is for m.giantbomb.com
...but the site was failing for a bit then changed to a 404 message. Too bad they removed the redirect but I'll just edit my bookmark I guess. Maybe it is related somehow though?
@rorie: Just a quick update... saw the same thing this morning. However, for some reason, I clicked on the GiantBomb logo and it loaded the page! If someone else who still has this issue can confirm that works for them, thats a workaround for whatever is going on.
