N4-Outage - Derby/Northampton Circuit
Posted by on 20 May 2018 07:58 PM
May 20, 2018 7:58PM BST
Investigating - Services Affected: - CIB and MPLS.

Nature of Issue: - Monitoring has detected a 10Gb link down between Derby and Northampton. We've raised the fault with the supplier and are awaiting feedback.

Characteristics of Issue: - Some packet loss may have been observed briefly but we operate a redundant topology and the core will have re-converged.

Next Status Update: - 20/05/18 at 22:00


May 20, 2018 10:24PM BST
Identified - Supplier is looking to arrange an engineer once remote checks have been made.

Next Status Update:- 21/05/18 at 09:00

May 21, 2018 10:00AM BST
Monitoring - Circuit has been stable for 8 hours now but we're still monitoring the Derby end. Traffic has be re-routed to ensure stability throughout the day.

Next Status Update: - 22/05/18 at 11:00

May 22, 2018 5:43PM BST
Monitoring - Diagnostics have identified a possible faulty XFP module
This is being replaced at 6pm today. The link is not currently carrying traffic so no customer impact is anticipated. This does not effect diversity or resiliency from Derby

May 22, 2018 6:53PM BST
Monitoring - The XFP has been replaced. We are continuing to monitor before adding traffic back to the link

Scheduled - Background Summary

Node4 are committed to delivering the best possible network service and uptime.
We continually invest in our infrastructure to meet customer requirements and capacity demands.
During the next two months engineers will be installing new core routers in to our data centres.
These core routers will support MPLS and Internet Transit services.

This work is not expected to have any impact on connectivity and cloud services however there will be increased risk during the maintenance.
The core network uses a resilient design, some of this resilience will be temporarily reduced during the maintenance window.
Engineers will also be costing out links and enabling new routing peers which has the potential to cause transient network connectivity while routing convergence occurs.

DC-3 Part 1 - 00:00-05:00 BST Friday 18th
DC-3 Part 2 - 00:00-05:00 BST Saturday 19th

Preparation work will commence at 00:00 with changes commencing at 01:00

We encourage all our customers to please check our network status page n4status.com during the maintenance updates and tracking.
