You cant un realm down yourself. The reason is because battle.net runs in accordance with your cd keys and local host ip. The main ip that goes straight to your home. Now if you went to starbucks on your laptop yea you can log in without realm down. however because your computer is linked by this, for some reason it cant be avoided.
Tips:
if your doing alot of diablo'ing, you need to have an extra set of cd keys. Switch out the cd key every 20 - 30 runs and you will not get realm down for more then 15 minutes ever....
I was in the same position, unless your a lead network hacker i doubt theres an easy soultion.
To avoid 12 hour realm downs without 2 cd keys, your games must be 20 - 30 minutes each game played.
The point is, You cant fix realm down. You can only avoid it
