I was having similar problems - here is the feedback I got to get realm status:
Blizzard has you covered:
http://www.worldofwarcraft.com/realmstatus/
If you use firefox....
https://addons.mozilla.org/firefox/1780/ Also, a buddy of mine gave me www.wizra.com to use - it sends the status to your mobile. I didn't want to post because someone accused me of being a spammer.
Good luck
