If you read the post Lynsey made she already said if maintenance runs long the event start (and in turn the finish) will be pushed back accordingly
http://forum.plunderpirates.com/index.php?threads/upcoming-maintenance.11691/ Aye, Thunderstruck hasn't actually started yet - we're waiting for the servers to come back up and giving everyone a while to get back in. Unfortunately we don't currently have an ETA on when that'll be, but I'll let you know as soon as I know! Obviously we'll be adjusting the end of Thunderstruck as well, so the Event will last the usual amount of time.
I saw the word awesome, and obviously thought you were talking about me. Looking forward to the event.
