I just switched to this pool today and my miners keep going back and forth from my backup pool. Is this normal?
Yes, it happens when pool switches to another coin.
If using CGMiner make sure the version is 3.3.1 or earlier (or it will be 5min before it switches back when pool is ready again).
That should be 3.5.0 or earlier. The 5 minute failover switchback was introduced in 3.5.1 to combat DDOS pool recovery behavior and make makes multi coin pool users pull out their hair.
