Elite Limited - Notice history

The issue affecting connectivity via Cogent on June 20th has been fully resolved.

We have received the following RFO (Reason for Outage) from Cogent:

“Customers in or transiting Slough may have experienced severe service degradation on June 20th between 12:18 and 13:32 GMT.

During a routine configuration change on one of our core routers in Slough, unexpected behavior occurred resulting in entirely unexpected side effects.

As soon as the issue was noticed, our IP Engineering department was involved to urgently resolve the issue.

Please note that as a result of this issue, internal processes are being carefully reviewed to identify areas for improvement and help prevent similar occurrences in the future.

We sincerely apologize for the inconvenience and appreciate your patience and understanding during this time.”

Actions Taken by Elite

• The affected peer was taken down promptly to prevent routing instability and protect service performance.

• Traffic was rerouted to ensure continuity for customers during the outage.

• Once Cogent confirmed the issue was resolved, Elite delayed re-enabling the peer until off-peak hours to avoid route convergence disruption.

• The peer was re-established during low traffic hours, with routing verified as stable.

We appreciate your understanding and patience while we worked to mitigate the impact of this incident.

Kind Regards

Elite NOC

Elite have re-established the peer facing Cogent, and we are now receiving full routing from the peer.

Traffic levels have normalised, and routing resiliency has been fully restored. We will continue to monitor for stability, but no further disruption is expected.

This incident is now resolved.

We will update this incident with the RFO from the transit provider once it has been received.

Cogent have confirmed the issue is resolved.

Elite will keep the peer down until low traffic hours to minimise any potential disruption during route convergence.

The fibre provider has resolved the issue and we have seen services return.

We will close off this issue. Services are no longer at risk.

The fibre provider has identified the fault and are working on a resolution.

We will update in due course once resolved.

We have received the following from the datacenter and are happy that all services have resumed to full capacity. Therefore, we will be closing this incident.

"UPS C2 module 2 has now been replaced and tested by Vertiv. UPS system C2 is now back on load with no issues and all alarms cleared. Monitoring of the system will continue to take place by on-site engineers over the rest of the weekend."

We have received the following update from the Datacenter:

"Replacement part required for UPS C, module 2. ETA to be confirmed. Load is currently supported across modules C1 and C3 at N+1 redundancy.

Update will be sent out as soon as the part is replaced and the module is back online."

As full functionality has not been restored, we will continue to hold this incident open and post status updates here.

Although we saw power return at circa 4pm to the affected feed, we are keeping this incident open, as the datacentre still has engineers on site. We will close this once they confirm to us the all clear.

We are starting to see power return to the affected feed.

We are monitoring this and liaising with the datacentre.

We will update asap.

We have had the following from the Datacentre operator:

--

The manufacturer is aware of the fault and they will send an engineer to the site.
Identified

UPS C2 fuse issue triggered the evacuation system; engineers investigated immediately and found no signs of fire. The faulty UPS was isolated, and the load was transferred to the remaining UPS. The site remained stable and is operating on N+1 in UPS C. The Manufacturer was notified and en route to the site.

We will update in due course.
