Incident: BT Wholesale Circuits

Posted: Monday, June 25th, 2018 at 11:03 by Mark Yardley

We are aware of an issue affecting a number of BT Wholesale leased line circuits. The issue has been raised with our suppliers for investigation. At the time of posting we are starting to see services restoring, however services should still be considered at risk. More information will be provided when available.

  1. David Brewis says:

    BT have identified an issue in the London Stepney Green exchange with a task raised for an engineer to attend and resolve today. We expect the next update at 17:00.

  2. Scott Morgan says:

    Our suppliers have attended site to investigate the issue.

    The engineer has conducted some preventative maintenance on the equipment and users may have seen another brief interruption to service during this work. However, we have not as yet been provided with a root cause for the previous disruption. We are continuing to escalate this with our supplier for investigation and RFO.

  3. Mark Yardley says:

    As part of ongoing investigation into this issue we are dispatching an engineer to perform pre-emptive maintenance on our equipment and to co-op with a BT Wholesale engineer. This work is scheduled for between 15:00 and 16:00 today. During the window services delivered via this supplier hand-off will experience a planned disruption to connectivity. We anticipate this should be no more than 10 minutes.

  4. Mark Yardley says:

    This work was completed successfully by our engineer in the previously mentioned window. However we are still experiencing intermittent problems with the hand-off. This issue is being escalated again with our supplier for further investigation. Updates to be provided when available.

  5. Gurinder Bansal says:

    Our suppliers have attended site and fixed a fibre break. Connectivity has been restored however services should still be considered at risk. We will continue to monitoring overnight and an update will be provided when available.

  6. Mark Yardley says:

    We have seen a recurrence of this issue again this morning. We are escalating the case further with our supplier. Updates will be provided once available.

  7. David Brewis says:

    With the recurrence of disruption to service, despite locating a suppliers faulty fibre last night, investigations continue to identify the cause. This has been further escalated in BT and we are currently still waiting on an update which will be provided as soon as it comes available.

  8. David Brewis says:

    Following hardware replacements and no further disruption experienced overnight we will continue to monitor service throughout today.

    Should a repeat of disruptions continue, further work involving BT and their vendors will be carried out moving service to new a configuration.

  9. David Brewis says:

    We continue to monitor the status of connections and observe no further drops at the exchange since 16:44 on 27th June 2018.

    Entanet will continue to monitor for an extended period whilst working with the supplier to ensure service returns to normal operation.

  10. Jamie Smith says:

    We have seen a recurrence of this again this morning. This will be re-escalated with out supplier Updates to follow once available

  11. Scott Morgan says:

    Our suppliers have advised that an engineer is currently onsite as part of this major service incident. Spare parts should be with the engineer shortly so that hardware changes can be made to help rectify the issue.

    We will update further once we have received confirmation that this work has been carried out.

  12. Scott Morgan says:

    We have received confirmation from our suppliers that a suspected faulty line card has now been replaced.

    We apologise for any inconvenience caused by this incident and we will continue to monitor.

    Please consider this as still at risk, until further monitoring allows us absolute confirmation that this is now stable.
