EDIT: ...Aaaaannndd, it's gone.
You can't count on the Canaan numbers being reliable for long periods of time, those are testers for the most part and they drop off within a few days. It's when people like cryptostar and sidewinder show up, that we need to be cheering!
HUZZAH FOR THE BARKEEP!
MINE ON WITH KANO-SAN!
However, I've certainly no complaint to make about that - they consistently point a lot of hash rate at the pool!

Just not exactly how much
I think their miners come default to this pool too, so if someone just plugs in to test without checking the config they'll hit here.
