Coinarmy is down last time I checked. Other pools aren't working either. My workers mined on Squiggie's pool for over 12 hours and didn't receive a single payout, despite receiving thousands of accepted shares. Not sure if Squiggie is a scammer or what, but his pool doesn't work. xpool was working somewhat-okay up until their network became overloaded, now you can barely get any shares (95% stale rate for me).

If someone's willing to share the knowledge, I have servers all around the world that I can host a pool off of.
