We experienced a short fibre outage on one of our fibre circuits between Bolton and Manchester overnight.
This started at 12:05am and concluded at 12:52am.
No maintenance was scheduled for this period so we are awaiting a RFO (reason for outage) from VirginMedia for the circuit.
Due to our redundant ring topology network, traffic was automatically re-routed via our other vendor circuits within seconds and no outages were experienced.
VirginMedia confirmed this was due to maintenance C00610077 which required rerouting of fibre cabling due to a railway bridge rebuild where the fibre currently travels.
We have lodged a complaint with our account manager as we were not informed of this maintenance.
