richmke, that speaks bad for the configuration on the miners, don't you have a backup pool? Like EU primary, useast as backup1, etc? This way when any falls it just switches till it is over.
I'm using the gridseed miners, and the controller does not have a failover option. Also, it apparently does not try to reconnect. I'm working on getting a raspberry pi controller, but for now, I need a stable mining pool.
