the ETH withdrawals being stuck is understandable because the ETH network has turned to shit ever since this cryptokitties crap started there and because ETH can not handle large number of transactions.
but the c-cex site itself also has some issue, I have been experiencing slowness, specially in their API which is so infuriating to sit and wait for a small response. luckily I don't have much there and I won't deposit anymore until they fix these issues or at least make an statement about it.
the ETH withdrawals being stuck is understandable - I call bullshit on this as while the network is bogged down like crazy due to the kitties, it is still functional and other exchanges are operating!!!
