Thank you! Clever approach to use temp. Does it autoswitch/check back to primary pool periodically, in case it comes back up?
Yes. It uses a session system, which is set by default to 3600 seconds. This means ccMiner is restarted every hour, so if it fails over it will mine on the secondary pool for one hour and on reset will go back to the primary pool... and if primary pool is still down, rinse and repeat.
You can change the session length in the config.
