Is Exascale down?

We are observing an outage on our Vodafone Broadband Interconnect, affecting broadband services delivered through this interconnect. We are in the process of reporting the issue to Vodafone’s service desk. Further updates will follow.

The incident has been raised with Vodafone’s service desk as a Priority 1 (P1) fault under reference FLT13710040 and escalated due to the repeated nature of the fault. We have confirmed that the fault is outside the Exascale network. Our LNS infrastructure is responding as expected, but the Vodafone interface remains hard down. Optical light levels remain steady, indicating a fault at the remote A end within Vodafone’s network site. Our next update will follow at approximately 1:00am BST on 7 October.

We have not yet received an update from Vodafone’s service desk. We are contacting them now to request an urgent update and will share further information as soon as it becomes available.

Vodafone has provided a new fault reference: NET13709772. The fault has been escalated due to its repeated nature. Vodafone has advised that a further update is expected within 10 minutes, at approximately 1:26am BST on 7 October. We will share further information as soon as it is received.

Vodafone has advised that they are currently assigning an engineer to attend the MCR11 and MCR12 network sites. The engineer will check equipment, cabling, SFP optical modules and chassis line cards as part of the investigation. We will provide a further update as soon as more information is available.

Vodafone reports that the affected circuit remains down. Field engineers are assigned to attend both ends of the circuit to check patch cabling, replace the optical transceivers (XFPs) and, if required, change the ports. Vodafone has advised that its next update is expected at 4:00am BST on 7 October.

In its latest update, sent at 4:14am BST on 7 October, Vodafone advised that both field engineers were still travelling to the affected network sites and that the circuit remained down. The engineers are to confirm their arrival and begin their checks in coordination with Vodafone’s network engineers. Vodafone has not confirmed service restoration.

In its latest update, sent at 5:51am BST on 7 October, Vodafone confirmed that an engineer had arrived at one of the affected network sites. A replacement engineer has been assigned to the other site, where Vodafone is arranging access. The circuit remained down, and Vodafone has not confirmed service restoration.

Service appears to have recovered. Our checks show that the Vodafone interface and BGP session are back up and have remained up for 37 minutes as of 7:25am BST on 7 October. The incident has been moved to monitoring while we await further updates from Vodafone.

Vodafone has confirmed that its engineers replaced an SFP optical transceiver, clearing the alarms, and that services are operating within normal ranges. Following this confirmation and our earlier interface and BGP recovery checks, this incident is now resolved. We apologise for the disruption.

Reason for outage – supplier findings Vodafone confirmed on 9 October 2026 that the outage was caused by a faulty SFP optical transceiver at its MCR11 network site. The transceiver was replaced and service was restored. Vodafone also installed an optical attenuator as a precaution to prevent potential transceiver damage from high receive power. Vodafone has not confirmed that high receive power caused the failure. We will continue to monitor the interconnect and report any further issues promptly. We have requested a formal RFO report from Vodafone, including clarification on the repeat nature of the fault and measures to prevent a recurrence. The incident remains resolved.

The interface, facing the Vodafone Wholesale Broadband network is hard down. We have logged the issue with Vodafone Service Desk.

Vodafone has identified the failed component within their network. A field engineer is currently on site reconfiguring the network to migrate our uplink to an alternative chassis at their MCR11 network site. This work is intended to bypass the affected equipment and restore connectivity while the underlying fault is addressed.

Vodafone have advised that their field engineer is expected to arrive on site at 9:30am today to move our uplink to alternative, operational equipment within their network. This work is intended to restore service, although restoration cannot be confirmed until the move and subsequent testing are complete. We will provide a further update as soon as more information is available.

This work is intended to restore service, although restoration cannot be confirmed until the move and subsequent testing are complete. We will provide a further update as soon as more information is available. No components were marked as affected by this incident.

Vodafone has confirmed that work is required at both MCRN11 and MCRN12. An engineer is currently arranged for MCRN11, and Vodafone has requested an additional visit to MCRN12 to complete the required port move. As the sites are close together, Vodafone has requested that the same engineer attend MCRN12 once the work at MCRN11 is complete. We’ll continue to provide updates as work progresses. Next update by 11:10 AM on 5 October.

The interface connecting Exascale to Vodafone’s network has recovered, and we are beginning to see customers’ routers reconnect. We are monitoring service recovery and stability. Full restoration has not yet been confirmed, and we will provide a further update once we have verified that all affected services have recovered. Thank you for your patience, and we apologise for the disruption.

We are monitoring service recovery and stability. Full restoration has not yet been confirmed, and we will provide a further update once we have verified that all affected services have recovered.

This incident has been resolved. Vodafone has confirmed that the circuit has remained operational and stable, with traffic passing normally for over 60 minutes. Vodafone will carry out a further stability check overnight and arrange a planned replacement of the affected card at MCRN11. Thank you for your patience. We apologise for the disruption caused.

We are currently observing the Uplink to the Vodafone DSL network being down. This is currently effecting all FTTP and SoGEA circuits.

It would appear the uplink(s) to Vodafone are online but the bundle is down. A field engineer has been dispatched by Vodafone to MCR11 at 8AM to investigate

Vodafone has advised that a line card within its network is reporting alarms. Attempts to clear the alarms by reseating the card have been unsuccessful. A replacement card is being collected from Vodafone’s stores. A field engineer will then return to site to remove the faulty card and install the replacement.

We're awaiting a further update from Vodafone Service Desk

The engineer is now on-site at the Vodafone network site MCR11 (Manchester 11), and is proceeding the replace the faulty optical equipment to restore the service. Once Exascale sees early signs of service recovery we will update this incident accordingly.

We have seen a large number of broadband services recover since the faulty optical equipment has been replaced by Vodafone engineers. We will continue to monitor for the next hour. If your service hasn't recovered, please email [email protected] and we will investigate further.

We're confident this is now resolved as we have seen all circuits recover.

We have reported the issue to Vodafone and we await further updates.

Vodafone are aware of a transmission fault in Manchester engineers are attending the site in the Metroplex Business Park

Vodafone have advised that there is a faulty SFP which has failed and requires intimidate replacement.

We have chased for a further update but one is not yet available.

Vodafone have advised parts are being sourced and engineering resource dispatched to replace faulty optical transmission equipment.

Vodafone engineer is now onsite attempting to resolve.

A second Vodafone engineer is attending the B-end of the circuit to carry out an End to End (E2E) test.

Vodafone have advised it is currently suspected to be one of the XFP’s. They should have the ETA of these engineers within the next 30 – 60 minutes – as soon as we have their ETA I’ll keep you informed.

The first engineer to arrive at one of Vodafone’s network nodes should be there for 16:30 and will begin investigations independently. The second network node is located at a data centre site, with an ETA between 16:30 and 17:00. Further updates will be provided if any of these times change, and will provide further updates once we receive any further feedback from Vodafone field engineers.

The first engineer has arrived and checked the equipment at the first network node, in which they have found no issue. They are en route to the other node at the data centre location. Further updates will be available within the next 60 minutes.

The engineer has attended the second network node, and has replaced the SFP on site. However, we are still seeing a Loss of Signal alarm. Vodafone transmission engineers are working on a slot change to assist in providing a resolution. Further updates will be provided once this work is completed.

The engineer has attended the second network node, and has replaced the SFP on site. However, we are still seeing a Loss of Signal alarm. Vodafone network engineers are working remotely with the Vodafone field engineer and are conducting loop tests to investigate further, 3rd line support engineers will be engaged if further assistance required.

We have seen the interface facing Vodafone recover, we’re also observing L2TP sessions reconnect. Traffic leaving the LNS is also building. We will continue to monitor.

We’re confident after speaking with Vodafone Service Desk the interface is now stable and has recovered after all the XFPs and SFPs have been replaced in path. If your broadband service hasn’t recovered please email [email protected]

We have observed a core router reload in Telehouse North, while the majority of the network has continued to function any directly connected circuits to pe0.lhr0.uk.as61049.net will have been interrupted. We are raising a case with Cisco TAC.

We are starting to see BGP sessions restore on pe0.lhr0.uk.as61049.net

We have seen stability for many hours. We are to schedule a future IOS XR upgrade to improve stability.
