It would be nice if CEX would weigh in on this. This is their official page. All my hashing power is down. Purchased and personal mining hardware.
Although they haven't yet, they do generally update their twitter after an outage..
https://twitter.com/cex_io#cex-squawk on freenode is the first place i check. Twitter is the second and their official page here is the third. I guess we'll have to sit and wait. At least people are still trading.
