As part of our commitment to service improvement, we would like to inform you that we will be performing planned critical maintenance as part of capacity upgrades on our core network
Maintenance window start: Wednesday 10th April 2019 23:00 GMT
Maintenance window end: Thursday 11th April 2019 06:00 GMT
Expected impact duration: The work will impact some of our DSL subscriber customers, and they will see an intermittent service within the maintenance, with a short period of down time. Service should be restored automatically but it may require a router re-boot. If after this action, service hasn’t been restored, please raise a support case in the normal manner.
UPDATE: the supplier code issues have been worked around and all tests are now available again.
We are aware of issues working with the APIs from the suppliers that’s affecting the ability to run diagnostics via the Merula portal (https://adslreports.merula.net); we are working on this now and will advise here as soon as this is resolved. Apologies for this loss of service.
RESOLVED: the fibre break was fixed at 8:53pm last night and all services are back to normal. This ticket is now closed.
UPDATE 15:50 — our supplier advises “in relation to the issue identified in Cambridge area regarding loss of service. We are still working hard to resolve these issues as a priority.
Due to heavy traffic in the area, this is impacting our ability to get into the pit location necessary to move services onto spare fibres. Traffic management is required to safely carry out the work and this cannot be implemented until 20:00 this evening due to local authority restrictions.
From 20:00 onwards we can commence repairs so we should see services begin to come back online overnight this evening.
Please accept our apologies at this time as we are treating this matter with the utmost urgency.”
UPDATE: 14:45pm — because of the amount of splicing work needed and the traffic management problems at this location, the ERT has been pushed out to 20.45 today.
UPDATE: 13:00pm — Traffic management is only permitted until 1530Hrs but traffic lights and barriers are on site ready to go. We’ve not been advised of a new ERT as yet.
UPDATE 12:30pm — work continues on-site at the node. Raised for traffic management. Has ERT for 15 minutes time but engineer still working and waiting for response from traffic management team.
Next update due at 1300Hrs.
UPDATE 10:31am — at 1008Hrs an engineer arrived on site. The overnight change was moving to new cable but there appears to be a fibre break. No ERT at present.
UPDATE 10:11am — this is now being treated as a high priority fault as completion has overrun and classified as a MSO due to the affect on Merula (and other) customers through this node.
UPDATE: we are escalating this for a substantive update as the works have again over-run their new completion time.
Emergency unscheduled works by one of our main backhaul suppliers have overrun and mean that one of our 1Gb links to London from the data centre here in Huntingdon is hard down. Traffic is being routed via one of our backhaul links but as this is slower you may see some slowness on some traffic until this work is completed.
We have been told that the work was due to finish at 6am but this has now been pushed out to 8am. We will continue to update here. Our apologies if this affects your connection(s).
Further to the outage yesterday and the corrective work by the carrier we will attempt to bring the link that failed back into service this evening. If all works to plan there may be a brief network disruption while the network reconverges. If the link fails again we will remove it from the network and continue work with our supplier.
The link was brought on line approx 12:30am this morning – However the previous issue re-occurred. This has been raised to the supplier who believe this is resolved this correctly now, We will plan a further maintenance shortly to bring the link back into service. In the mean time there is no reduction to service – but there is a slight reduction in resilience to our Manchester PoP
During planned work deemed low risk by a supplier they managed to inject a loop into one of our links. This caused a significant level of packet loss into our network at approx 22:50 on 31st January.
The link was removed from use and service was resumed albeit with reduced resilience. The issue has been reported to the carrier who have identified a potential problem and resolved this.
