It's bound to get hit with DDOS and other attacks often since it's an exchange as well as a pool.
I noticed drops in my graphs over xmas (i'm that thrilling) but my miners were still hashing fine, they were just throwing half those hashes to my secondary pool. Which, for now, is BTCguild for now until my hosted cexio hashes match my physical mining rig. Then I'll have a race.
Hilariously, I was just now going to cexio in order to post a screengrab of my charts so y'all panicky types can see what happens when hosted Ghs speed drops there (it overmines afterward to compensate), and how much daily speed gain you can make selling all the mined NMC for GHS (about 1-3%).
But hey guess what? Instead I'm seeing a cloudflare error 524.
BUT my two mining rigs pointed there are currently perfectly happy. There's occasional stratum connection interruptions, but never for many seconds, and cgminer is sufficiently intolerant of laggy pools to switch to my failover pool/s real quick.
So yeah just 'cos ghashio is down doesn't mean you're not mining in it!
And if you fear it, use btcguild instead for your own miners, and throw spare NMC at cexio as a bonus mine-on-the-side.
