I have
http://us.ozco.in:8331 set as a backup, but that does not appear to work either and my 2nd backup (bitcoinpool) no longer exists. Any suggestions for a backup ozco pool or a different pool?
Yep those 8331 ports shouldn't be working anymore. They've shut off the old GW protocols. Ozcoin has 4 nodes now:
stratum.ozco.in:3333
us.ozco.in:3333
au.ozco.in:3333
eustratum.ozco.in:3333
Pinging them, it seems that stratum.ozco.in and au.ozco.in share the same IP, so it looks like it's really only 3 right now. As for pool strategy, keeping 2-3 Ozcoin nodes and then 1-2 other pools would keep you very well protected from downtime.
