    We are continuing to investigate reports of packet loss, however we would request any affected customers to provide the service desk with supporting evidence in the form of pathpings or winMTR data to allow further troubleshooting

  2. david labouchardiere says:
    December 11, 2020 at 10:17

    Investigations into the packet loss reports are ongoing. We continue to ask that any affected circuits provide us with supporting evidence using winMTR or pathpings to assist in troubleshooting

  3. david labouchardiere says:
    December 11, 2020 at 11:58

    Investigations are ongoing into the reports of packet loss. We are in talks with the supplier requesting they troubleshoot on their site based off the evidence supplied so far. We will update once we have further information from them.

  4. david labouchardiere says:
    December 11, 2020 at 14:15

    The supplier is currently investigating the reported issue and has raised the case to their networking team for further assistance. We will continue to push for further updates. At present, no further evidence is required from affected customers.

  5. david labouchardiere says:
    December 11, 2020 at 17:01

    The supplier is continuing to investigate the issue on their side and further updates are expected in the next hour.

  6. peter butler says:
    December 11, 2020 at 18:42

    Investigations with our supplier are continuing but, unfortunately, we do not have any solid updates or timescales for resolution at this point.

    We shall continue to chase this over the course of the evening and post updates when they become available.

  7. Jonathan Clarke says:
    December 11, 2020 at 22:16

    Investigations into the packet loss reports are ongoing, BT advise they are chasing their 2nd line team for updates. We are continuing to chase for updates, as soon as we anything further, we will update you again.

  8. Jonathan Clarke says:
    December 12, 2020 at 07:27

    BT advise that packet loss was observed when testing. BT advise that the there is a potential issue on their core network. Further troubleshooting will be required, however, the issue is only present within core hours.

    As of this, BT are going to be continuing testing throughout the day. BT’s 2nd line team are engaging with their 3rd line team for further assistance today.

    We will update once we have further information from them.

  9. Peter Butler says:
    December 12, 2020 at 10:21

    BT advise that as the packet loss does not appear to occur overnight this has been passed to their day shift to investigate today. Intermittent loss has been seen again this morning so they are continuing to trace the root cause of the issue.

    Our escalation point is aiming to get an update to us by 1200 today, so we will aim to update via this post shortly thereafter.

  10. Peter Butler says:
    December 12, 2020 at 14:21

    BT have advised that the intermittent packet loss that was seen at 0800 this morning has not been present since, which has hindered progress with their fault finding.

    Investigations continue and BT expect to be able to provide a further update by around 1600 today.

  11. Adam Wilson says:
    December 12, 2020 at 19:41

    We have provided further evidence of packet loss to BT, and this is currently being reviewed. Further updates will be provided as soon as they become available.

  12. Jonathan Clarke says:
    December 13, 2020 at 07:00

    BT have advised that their 3rd line team are not observing any packet loss whilst testing. We have been advised that they will continue to troubleshoot out of hours, however, mentioned that they believe that the packet loss will not present itself until Monday morning in core hours.

    Our escalation point within BT has stressed to them that if this can be resolved before Monday and ensure us all efforts to resolve this before then are being made.

    A Further update will be provided as they become available.

  13. Jonathan Clarke says:
    December 14, 2020 at 07:00

    BT advise that 2nd line and 3rd line team have been monitoring the BTW network for signs of packet loss. In the last 48 hours no packet loss has been observed. As of this, BT have been unable to replicate the issue out of core hours.

    BT’s 3rd line team are monitoring the network this morning for when the packet loss reappears, to ascertain where in the network the issue lies to resolve.

    A Further update will be provided following BT’s troubleshooting.

  14. david labouchardiere says:
    December 14, 2020 at 13:22

    BT advise they have seen no further packet loss today and our monitoring confirms this. BT are continuing to investigate and have setup additional monitors to assist this. We will provide a further update once we have any more information.

  15. Peter Butler says:
    December 15, 2020 at 15:43

    We have been receiving further reports of packet loss coming into the desk as of around 1430 today. We have alerted BT to this and they have confirmed that they are looking into this.

    We shall provide further updates once they are received.

  16. david labouchardiere says:
    December 16, 2020 at 13:22

    We are continuing to push BT for further updates on their investigation into this issue and provided additional details to them to assist in their testing. We will provide a further update once we have any more information.

  17. Peter Butler says:
    December 16, 2020 at 16:07

    We are continuing to provide examples of circuits affected by this issue along with evidence to BT to try and push this to resolution, we are also engaging escalation points within BT to ensure this is treated at the highest priority on their side.

    We shall continue to chase and provide updates when available.

  18. Peter Butler says:
    December 16, 2020 at 20:20

    Investigations are still ongoing with BT with our NOC team also assisting and investigating the traffic as it enters our network to ensure we are looking at the whole picture.

    Unfortunately as the loss seems to occur predominantly during core hours it is likely to be the morning before any further update can be provided, so a further post will be made tomorrow morning or upon the receipt of further information.

  19. Peter Butler says:
    December 17, 2020 at 08:51

    Unfortunately no issues could be found overnight whilst the issue was not manifesting itself so this has now been picked back up by the day shifts on both BTs and our side.

    We have multiple circuits being monitored which allows us to see when the issue is present so will update further when more information is available.

    No further evidence of the issue is required from customers at this point.

  20. Peter Butler says:
    December 17, 2020 at 11:39

    An emergency change is currently being planned in order to assist with troubleshooting the issues curently being seen. This is being discussed at present so that it can be decided when best to carry this out.

    A further update will be posted at 1500 or upon receipt of further information.

  21. david labouchardiere says:
    December 18, 2020 at 09:28

    We are seeing no further signs of loss following the emergency work carried out yesterday and believe this issue to now be resolved. Any remaining customers that are affected are advised to reboot their router before calling into the Service Desk. We apologise for any inconveniences caused by this outage

Due to on going improvements to the power infrastructure within the BT POP’s, we are preforming exploratory work before refreshing the ATS and UPS for this site.

BT will be undertaking maintenance work within the above window which will require the tracing of some cables on site. This will involve the removal of a panel on a DC inverter to visually inspect the connectivity within.

We will not be attempting anything other than a lid removal and visual inspection and the risk to impact during this window is considered low.

    This is still being investigated. However, we expect a Nokia engineer on site at approx 18:45 this evening and a replacement card will hopefully help to resolve the issue. Further work is ongoing with the current engineer on site, to try and restore links in the meantime.

  2. jbiddulph says:
    November 28, 2020 at 20:30

    We are currently still awaiting a part to be delivered so we can restore complete service. This was unfortunately delayed and is due to arrive for 9:30PM. Since the previous engineer has had to be relieved due to working on this issue since 8AM, we are also dispatching a new engineer to help fix the fault.

    In the meantime, we are continuously working on trying to restore this remotely. A further update will follow promptly when available.

  3. jbiddulph says:
    November 28, 2020 at 23:25

    All Services should now be restored. We are seeing the core device that was offline for this to now be online.
    A full RFO will be provided at a later time to advise of the fault cause, and fix. If you have any further issues, we advise to fully re-boot all services.
