During this morning's RPN maintenance on 6 switchs we have noticed a disconnection on our RPN-SAN hosted in DC3 (all SAN between 17 to 31 and SAN-4).
The disconnection lasted 5 minutes.
It was not planned and necessary actions were done during the update to prevent this. Unfortunately we have found an unplanned case that interrupted the service.
We have added this case to our process for the next maintenances so that it does not happen again.
