At 19:25 we have received notifications from our monitoring system about a minor outage on connectivity at DBC.

After investigation we have found one of the optics reported fault causing several VLANS to flap between VRRP primary to VRRP secondary which caused some connectivity issues.

The offending port is shutdown at 19:30 and VRRP completely restored at 19:40.

Currently we will be monitoring the situation and we will be planning in to replace the defective optic.
