Olilo - Notice history

CityFibre believes that all services have now been restored. However, we are currently awaiting confirmation from the on-site engineers that the splicing works have been completed and that they are fully hands-off. Next update at: 08:30 04/11/2025

Engineers remain on-site and are continuing with the splicing works. CityFibre’s NOC has confirmed that the majority of services have now been restored. However, due to some delays encountered in the field, full restoration is now expected by approximately 07:30. The Major Incident Team is closely monitoring the situation to ensure the issue is fully resolved. Next update at: 08:00 04/11/2025

The Major Incident Team has identified the root cause of the incident as a fibre break, resulting from a high-voltage power issue that caused the cables to melt. Due to the extent of the damage, engineers are required to remove the existing cable and install a new one. The estimated time for full service restoration is approximately 8 hours; however, some services are expected to restore prior to the completion of the works. The Major Incident Team is closely monitoring the situation to ensure the issue is fully resolved. Next update at: 03:30 03/11/2025

The Major Incident Team have identified the cause of the incident as fibre strike and are currently working to restore the services. The ERS engineers are currently on-site to repair the fibre. The Major Incident Team are closely monitoring the situation to ensure the issue is fully resolved. Business Impact: Approximately 3000 FTTH, FTTP and Dark Fibre services are down.

RFO – DDoS Incident

Date/Time: 8th October 2025

Impact: Intermittent connectivity and packet loss across parts of the network.

Duration: ~45 minutes

Status: Resolved

Summary:

At approximately 14:00, our network began experiencing a large-scale Distributed Denial of Service (DDoS) attack targeting our edge infrastructure. The attack caused intermittent packet loss and service degradation for some customers.

Actions Taken:

• Identified malicious traffic patterns.

• Temporarily withdrew our route servers via LINX and LONAP to isolate and contain the impact.

• Engaged automated DDoS filtering which successfully mitigated the attack and restored stability.

Preventative Measures:

We’ve implemented some changes to our DDoS defence system and filtering rules to mitigate this in the future.

Status:

All services are now stable and fully operational.

The DDoS attack has been fully mitigated. Services are now confirmed stable and performing as expected.

We’ve implemented some changes to our DDoS defence system to mitigate similar events in the future.

Thanks for your patience while we dealt with this one 💪

We’re now monitoring the issue closely, and the reduced peering will remain in place while we make sure everything stays stable.

We’re currently being targeted by a DDoS attack which is causing some disruption.

Our network team is actively mitigating and things should start stabilising soon.

Please bear with us while we get everything back to normal 💪

We’ve run checks on our side, and the increased latency only seems to be affecting certain CityFibre areas (Scotland).

Since there’s no actual downtime, this isn’t considered a fault on their end.

The best we can do for now is wait for CityFibre to resolve it, likely as part of ongoing upgrades or network improvements.
