Goddamnit, it's doing it again.

So, at home, I cannot connect to anything at worldofwarcraft.com (forums, server status, hell, the game itself), nor will Firefox admit that Livejournal is up (I'm posting this from work).

Same with Slashdot, Crispygamer, and a handful of other sites. It just times out.

But I can connect to google, yahoo, most of the webcomics I read, etc.

And while I can't get a connection to World of Warcraft, I can connect to City of Heroes to play it.

So, seriously, what the fuck? I've tried a few different things (ipconfig /dnsflush, for one) but they don't seem to help. Pinging the relevant servers just shows that it times out on ping, and tracert doesn't give me any extra useful information.

It seems to be an intermittent problem, as I was able to connect to LJ and WoW earlier in the day. But what the hell is causing it?

If anyone has any ideas, I can still read your responses (as LJs e-mail notification still seems to be working), but I will be unable to reply until I can once again get a connection to LJ from my home computer. (Actually, I fully expect that within five minutes of me posting this, my computer will go back to normal, but I still want to know why the hell it's acting up this way.)

Anyone have any thoughts on the matter?
