Unable to connect to Battlegroup it seems

I've multiple accounts and it seems none of them can connect to the Cenarius or Blackwater Raiders servers, both realms are listed as up and I have connected to them once last night from my current location. I am currently vacationing at my sister's house in another state but the fact that I connected last night on the same computer and I can access other realms leads me to believe that it's the battlegroup cause both cenarius and Blackwater Raiders realms are on the same battlegroup.. pls help me connect to my main character realms so I can enjoy WOW while i'm on vacation..
