Blizzard's US websites and all related web services are currently down for a scheduled maintenance and should be up at around 5am PDT. This means that all US versions of Blizzard sites such as World of Warcraft, Starcraft 2, and web-accessible services such as account management and the Armory are down. Maybe when they come back up, we'll see some more visible changes to the site such as the aberrant switch to a Wrath of the Lich King theme of the official forums. Or maybe there'll be an abundance of small changes such as the minor tweaks to the Death Knight information page. Then again, it could just be nothing but a regular maintenance. We'll see in a few hours. At least Blizzard was nice enough this time around to actually put up a sign to say they'll be back.
