I just tried to look at 101fwy (http://www.101fwy.com/) and it's been replaced with what seems to be an ad for the web host or something. Too bad, they had some really nice boards.
I've seen that a few weeks ago. There's this thread where you can find the new (temporary ?) urls : http://www.esc101.com/free/101.php?res=808. You can still find a few boards throught http://www.esc101.com/, http://siokara-7.ath.cx/101/, and take a look at 102 freeway (http://ventura.beerbar-ts.com/).
So what happened to it? Did the domain get snagged by squatters like what happened not too long ago with iichan?
