This Tuesday(19/02/13) we will be having server maintenance. This is a big maintenance(12 hours). This is only my guess(so don't take it as word from blizzard) but I assume this is because of global play coming in to Starcraft 2 this week. With global play coming in players from other regions will be able to play on the US servers and speak with people on said US servers hence something may be needed to be done on all 3 Bnet games.
Course it also could be because we just had a major patch and blizzard want time to look over and hopefully fix any issues with the servers.
Server down will start at 1:00am PDT which is:
Australia & New Zealand times/dates:
5:00pm - 5:00am Perth
7:30pm - 7:30am Adelaide, Darwin
7:00pm - 7:00am Brisbane
8:00pm - 8:00am Sydney, Melbourne, Hobart, Canberra
10:00pm - 10:00am New Zealand

Note that this maintenance will go for 12 hours, till 1:00pm PDT (Baring any unforeseen issues that may extend maint)
Also remember that blizzard does this while there is the least amount of connected players on the servers, while it is unfortunate that it falls in a good play time for us it has to be done.
Lets keep it civil and show that while downtime does indeed suck, we can still be a good community!
Taken from Service Status forums:
We will be performing scheduled game maintenance for Diablo 3 on Tuesday, February 19th. Maintenance will begin at 1:00 AM PST and is expected to last for 12 hours. During this time Diablo 3 will not be available for play. In addition, many web services will be unavailable.
Thank you for your patience.
