This is how it started with mtgox and cryptsy
all the yearly volume of coinexchange is not even as big as volume of one day either of those two websites had! how can you even compare the two together?
besides it is a tiny exchange with limited server resources on a shitty server to cut the costs of business, if they didn't go down like this you should have been surprised. their quota is probably reached and they have to pay for more
