You might wanna try using the WoW repair program that comes with the game. This will scan through the folders that the game is in and see if anything got corrupted. If this does not work you can ask on the official WoW forums in the tech support section and they can try and help you.
If this happens on a Tuesday, then it could be that the realms are just down for maintenance.

You need to open up your realmlist in your world of warcraft folder and replace all the information to "set realmlist us.logon.worldofwarcraft.com" save it and then restart wow.
It differs depending on which continent you are playing on. For instance, In Europe the realmlist would be: "eu.logon.worldofwarcraft.com" And in US: "us.logon.worldofwarcraft.com"
The realmlist is a text document in the game folder than contains the information necessary for the game to contact the servers.
Go to their forums. (Which is currently down.)
