Your session has expired

I can't connect to iTunes Connect today. (Wed 4th Sep 2013)
Sometimes it takes 2-4 minutes to proceed to the next page or login, and at times I get a Gateway Timeout. Meanwhile, my session has expired. I do it again from a beginning.
Very annoying!

My boss said, "Hey, can't you yet release it? so late! hurry up!".
A new wasted working day ... Thank you Apple.
