I think amazon recently changed their disbursement schedule. It use to take hours to get the disbursement email after i initiated the transfer but now i get it within 15 minutes.
I have seen disbursements at 9pm. It always changes. I wouldn't assume the account is suspended. At least not yet. If the money is not disbursed by tomorrow, then that is a different story.
From your time post, you are on the east coast. Amazon is on the west coast. So, 5:30pm your time is 2:30pm to Amazon.
even if the account was suspended the money would be disbursed if amazon had disbursed that days money. They would then reverse it
Your account id fine for now. Amazon recently changed the times they disburse the money. It used to be 6 o'clock in the evening every time. Now its done around 3 am.
