api.bitcoin.cz and api2.bitcoin.cz still point to the old compromized servers at OVH and I'm surprised they're still running. Who knows who's controlling them tho (if anyone at all).
There hasn't been any information about this whatsoever so I can't blame you. Oh Slush, where art thou...
Well thing is sometimes api2 only works others only stratum works its a toss up only way I've been able to get it stable was to configure it to monitor both at the same time. I can probably add stratum2, stratum3, and a BTCGuild just to be safe though.
