This evening at 23:00, we will perform a reboot of the standby routing engine in one of our routers in the Haarlem zone. Following an unexpected software issue, a routing engine failover took place today, leaving a reduced redundancy in this router. The router itself has further redundancy in it's counterpart, so there's little risk of failure. However, redundancy must be reestablished. We don't expect any services to be impacted.
