NTA - Service Outage – Incident details

RFO 27/06/22

Whilst investigating the root cause of last week's faulty flapping link, the link was accidentally brought into service by our upstream suppliers and caused the issues to re-occur.

This was identified and quickly removed from service again and service restored.

However, as a result of restoring everything to a normal operating situation, a further shutdown was implemented to enable full functionality services to resume.

We are working closely with our suppliers to make sure changes are never implemented, or any attempts to do so happen during an investigation, that may interfere with the normal operation of our services during normal working hours unless specifically instructed.

This will only be in the case where it would be operationally critical.

Any network changes will continue to be scheduled and notifications sent as per our normal procedure

We just resolved the issue!

We implemented a fix and currently monitoring the result.
