PSA: Blizzard says "WoW, SC2, & D3 on NA servers will be down for maintenance"

Sounds like Bnet is going down in NA today Thursday August 1, 2013 at 7:00 pm EST, see Tweets below:

"Maintenance is scheduled for tonight so #WoW #SC2 & #D3 will be unavailable during this time. Start time for the maintenance is 7pm AEST."

"Yes KR or any other server outside of NA will be fine."

Edited to add:  "NA servers, and it looks like a 6 hour maintenance window"
