I believe that every year Fastlane goes down for "maintenance" the night that results are sent out. This year the due dates were moved up, so do you think that this could be us?
"03/09/16 - FastLane will be unavailable from 12:01AM ET to 8:00AM ET on Saturday, March 12 for scheduled maintenance. We apologize for any inconvenience."
The "important Dates" page says early April for notifications, so I'm pretty sure that I'm just wishfully thinking. Wouldn't that be nice though? I always do a great job not worrying about it until March rolls around, then it's hard to keep it off my mind...
