We were offline for several hours this week. For each hour we're offline, hundreds of deposits are queueing up to be processed. Yesterday our Bitcoin infrastructure was offline for hours, while our marketplace was still online. This added to the size of the transaction queue. The sudden halt you're seeing is that all recent deposits/withdrawals are thousands deep in a massive queue, which our upgraded infrastructure will be able to process faster than our current system. We're working hard on it, and will update here when everything is confirmed to be flowing quickly. Until then, refresh deposits every hour to see if your transaction has been processed. Refreshing more often than that just slows the process down for everyone.
