Olilo - Notice history

CityFibre are pleased to confirm that the issue is resolved.

The power issue affecting the equipment has been rectified, and services have been restored.

Thank you for your patience during this incident.

The Major Incident Team are currently investigating an incident impacting a number of services within the St Albans area. An FLM (First Line Maintenance) engineer is onsite and has commenced initial investigations. We are working to identify the cause and restore services as quickly as possible.

Next update at: 22:30 09/07/2026

CityFibre have confirmed this is a MSO (Major Service Outage) impacting approximately 2139 Services.

More updates to follow.

The engineer arrived on site, has replaced the faulty part with services restored. We are however going to continue to monitor to ensure the links are stable, so far services have remained stable.

After several talks with the vendor, we have confirmed the earliest time for the faulty part replacement ETA is 03:00AM. Due to the location of the nearest part being sourced from, this is the earliest we can get the part for arrival to resolve the intermittency, providing there are no delays by traffic. Once this has arrived the engineer will work towards restoration on a co-op call with the vendor. Next expected response: 03:30AM.

We are aware and have been working on an network fault causing intermittent TLOS for a number of services. This has been identified to be a faulty part in the network that we believe to be resolved earlier this afternoon through a re-seat. As it stands the customer connections are still flapping, so we are in coordination with the vendor on replacing the faulty part causing the outage. There are no specific ETAs at this moment in time, and estimates are this will be resolve in the early morning, but we are pushing to get this fixed asap. Further updates will follow as soon as they are available.

CityFibre have confirmed this is currently affected by an emergency change that is affecting customers in Crawley, we have a time window of closure at 19:30 today.

The remaining 4 customers have now been successfully restored after the engineers found a bad splice at a track joint. All services back online. NOC will continue to monitor to ensure stability.

All fibres have now been spliced however 4 services remain down. Engineers are attending the affected drop node to test further. Updates to follow.

Engineering still on site working through splicing fibres together. More updates to follow.

Damaged cables have now been replaced. Engineers are now beginning splicing fibres back together. Further updates to follow.

Engineers are back on site this morning implementing the cable replacement. Expected time of fix is around 13:00 today. Further updates will be provided.

Location of damaged fibre has been confirmed. It appears as though a high sided wagon has caught the cable and brought it down. Repairs unable to take place tonight due to health and safety restrictions. Cable route is on single track road and runs through trees. Multiple engineers will be reattending tomorrow morning to carry out a full repair. Further updates will be provided when work resumes.

Service has now been successfully restored following intervention from the onsite FLM engineer. The issue was identified as being caused by elevated temperatures, which resulted in equipment impact. Once conditions stabilised and the FLM completed the necessary checks, services returned to normal operation. We will continue to monitor the situation closely to ensure ongoing stability and will provide further updates if required.
