Planned Core Network Maintenance

The maintenance is now complete. Thanks for your patience.

The scheduled maintenance is now underway. We'll keep you updated on our progress.

Dear All,

Please be advised that there will be essential maintenance and upgrade works being undertaken at our London Central and Telehouse North nodes on Thursday 29th of Jan, starting at 20:00pm, and ending on the 30th of Jan at 03:49am

The works to be carried out in this window will include:

• Staged upgrade to core routing MPLS at NLC and THN
• Dark fibre handling adjustments, NLC to THN routes
• Further 100Gbps+ integration to core
• 25Gbit Upgrade to Handoff Service
• Minor power system maintenance
• On-load generator test

These are necessary works that will ensure ongoing high-quality service delivery to all customers.

Please treat this window as 'at risk', though it is considered a low risk operation with no impact to customer services unless specifically notified in advance.

The small number of select customers that will see minor service interruption as route processors are upgraded will be contacted separately.

You will receive notification via email with more information where necessary.
