Everyone will have failed over to their 3rd pool.
The script restarted it immediately, so everyone should be failing back within the next 5 minutes.
Sorry about that unexpected restart.
What's a good recommendation for the third pool?
Honestly the Kano pool is almost never down (and comes back up so quickly) so that anything you put in your 3rd pool will never collect enough hash to ever payout anything. I use to have a PPS pool as my 3rd but after a couple of years I realized that all I did was add a little dust on that account. Since then I just changed over to another Kano node as my 3rd. That way I don't have to wait for my miners to switch back when the pool is rebooted and back online
