UPDATE: BoLS is back, as are the conspiracy theory trolls. Take a look at their forum. Sheesh.
Loken at Apocalypse 40k has a brief report about several prominent 40k sites that are hosted by Google being down.
Here's the post.
The DCMA is a weird and powerful thing, and its abuses are well documented. It's still too early, in my opinion, to positively blame GW for these sites going down, but it doesn't look good.
I'm not a kneejerk guy, so I won't be immediately selling off all my Warhammer 40k stuff, but then again, what are you really saying about yourself if you support a company that takes such a heavy handed approach to their tiny niche audience?
Again, it's still a bit too early to know what's happening, but it should be an interesting week.
