Only Penny Arcade (the whole site, not just the forums) seems to be affected. Started yesterday in the evening, navigating to the page brings up "Safari cannot open the page because the server cannot be found." It doesn't seem to be making any attempt to load the page, just immediately spits out the error. I have a sneaking suspicion this isn't actually a problem on your end, but I figured I might mention it. I'm connecting via wifi and mobile networks in Taiwan. Desktop connection works just fine.
