BioWare had an Unscheduled Maintenance. Apparently to fix a serious economic exploit
We will be deploying a patch and performing an unscheduled maintenance this Friday, April 27th, 2012. Patch notes will be made available shortly after the servers come back up.
The servers will be down for four hours on Friday, April 27th, 2012 from 2AM CDT (12AM PDT/3AM EDT/8AM BST/9AM CEST/5PM AEST) until 6AM CDT (4AM PDT/7AM EDT/12PM BST/1PM CEST/9PM AEST). All game servers will be offline during this period. This maintenance is expected to take no more than four hours, but could be extended.
And here are the patch notes:
