As mitigation, renters that believe to be affected by this can ask extra hours to their rig owners.
Are you suggesting that rig owners should compensate renters for a problem caused by your system???
Are you suggesting this not to be the correct way?
So a renter aka (Paying Customer) who paid you for hashrate, you failed to deliver should not be compensated?
You do understand that this is your responsibility to your Customers as a rig leaser.
I hope that you also understand that when betarigs is down your rigs are mining coins on your choosen pool.
In this case betarigs failed to deliver and not the server owners, you are right that the server owner mined at his/her own pool during that time so time compensation is in place.
