I'm getting the no stratum notice too, even though I'm running the latest cgminer and have been on stratum for quite a while.
Now I don't understand your problem. cgminer looks ok ("Switching pool 0 ... to stratum+tcp ...").
Yeah, I have been running on stratum for a while, but I was getting a notice on the website that claimed I wasn't. It seems to have stopped now.
Btw no need to run backup pools for api, api2 and api3 - all three IPs are using the same stratum backend...
I'll change my startup script then
