Earlier today we had an unusually large spike in withdrawal requests that set off an automatic shut-off designed to prevent loss of funds in case of a hack. There was no hack, just lots of people trying to withdraw all at once. This has disrupted the normal flow of coins through the Silk Road wallets, so we are currently behind about 6 hours. We are working on expanding the throughput of the system to catch up and get withdrawals current, but it may be some time before we get there. I'll keep you posted on this thread. -DPR
