Hi,
The Producer should be online/sync when needs to create the block so… there will be no issue if from time to time ur producer will be offline (if has not blocks asigned).
Of course it’s better to have another node in standby ready to work as a producer (u can configure another private node for this - configure as a relay but don’t register it)
Some one shared a script for Producers
!!! Remeber u can’t run 2 Producers same time !!!
