Problem with network connectivity in SDC1, Dronten

UPDATE: 16:15 19/03/2019

Today we faced with a software bug on one of our Cisco routers at SDC1 in Dronten. During the investigation of the problem, the affected route was switched over to the standby CPU but the problem was not completely solved.
After the emergency software upgrade and full reboot, the router became stable again.

We apologize in advance for any inconvenience this might cause.
For the official RFO, please contact our NOC team.
