What a bunch of bozos....they didn't subscribe to CloudFlare or other anti-hacking service ? Even I have it for my blogsite !! Are they being cheap or stupid ?
The best explanation of what is REALLY going on (from Andreas Antonopoulos): It’s like a retail customer showing up at a customer service desk with a photoshopped receipt and trying to get a refund. Mt. Gox was fooled because they didn’t check the receipts against the blockchain. Others are not fooled, but today they saw a flood of such attempts, as if retail shoppers showing up with shoeboxes of falsified receipts hoping to cash in on this problem. These other exchanges are now dealing with a flood of these which is delaying legitimate withdrawals and some suspended withdrawals in order to check their implementations In about a week I expect all the exchanges will have robust and correct implementations, as the network has now been stress-tested. Some will resume quickly, Gox might take a bit longer to resume. In the end, the entire industry will be more resilient. http://www.coinspectator.com/andreas-m-antonopoulos-gives-insight-into-the-current-bitcoin-chaos/ So not a DDOS which can be solved by CloudFlare (which Bitstamp has implemented as well)
