Monitoring — The supplier has carried out further optimisation to the network and are now seeing services restoring for the affected customers. They have advised that as the there is still an open incident on the Leeds to Sheffield link, services should be considered at risk until the link has been brought back into service. They will continue to update this incident until that risk has been fully mitigated. They have asked that for any customers still experiencing an issue they power-cycle their equipment before raising a support case via the normal channels.
