Is it still stable?

Westhash and Nicehash orders keep getting canceled after a half hour or so when I point them at Slush's pool.  I've been forced to only use CKPool for my rentals :-(

I had the pool "verificator" tell me the diff was too low.  After several tests it may say it is ok, but usually it reports that slush's pool is "incompatible" and occasionally that it is having connection problems.

If anyone wants to investigate, this Pool verificator can be found on the new order page only, an is only available to logged in users, but registration is free and you dont need to fund the account to get to the that page.

I'd love to know why Westhash + Nicehash can't mine at Slush's pool for me!
