IDENTIFIED

Dear Customer, Node4 has temporarily taken its N-able N-central platform offline following a critical security notification from N-able. N-able has instructed operators of on-premises N-central environments to take their servers offline while N-able conducts further investigation and remediation takes place. N-able currently states that it has not identified active exploitation of the vulnerabilities. This is not a security incident originating within Node4. What is N-central? N-central is a third-party technology platform supplied by N-able that Node4 uses to help monitor and remotely manage elements of some customer IT environments. Depending on the services you receive, it supports activities including monitoring, automated alerting, remote management and automation. Because the platform has privileged access to customer environments, we have taken the precautionary decision to keep it offline until N-able confirms it is safe to restore and Node4 has completed its own technical validation. What does this mean for you? Node4's support services remain operational and customers should continue to raise incidents through their normal support channels. While N-central is offline: • Automated monitoring and alerts may not be available. • Remote-management activities may take longer or require an alternative approach • Automated activities delivered through N-central may not run. • Issues normally identified proactively through N-central may need to be reported directly to Node4. • SLA measures specifically dependent on N-central may be temporarily impacted. This action has been taken to protect our customers. We believe a temporary reduction in these capabilities is preferable to continuing to operate a privileged management platform contrary to the manufacturer's security guidance. We are actively monitoring the situation and will restore N-central only when it has been confirmed safe to do so. No action is required from customers at this time. We will continue to provide updates as further information becomes available. For the latest information directly from N-able, please visit the N-able Incident Status page: https://uptime.n-able.com. We understand you may have questions or concerns following this update, please contact your Engagement or Account Manager in the first instance. Kind regards, James Rentoul SecOps Manager - Security Operations Node4

Description

Description: On 10/11/2026, the Data Centre Operations Team will be overseeing HV maintenance inspection and service work at Northampton DC4. Throughout the maintenance window, no service impact is expected, however the DC4 Power Feeds will be 'At Risk’. Impact At Risk - 10/11/2026 08:00 to 18:00 At Risk – During the HV maintenance inspection and service work the mains power and HV power systems will be switched off and the site will be transitioned to generator power supply for the duration of the work. This means there will be no mains power backup during the work. The site mains failure tests are conducted quarterly and no impact is expected. However due to the reduction of resiliency the service is deemed at risk. Support & Feedback Our Data Centre Operations Team will closely monitor the work and will do everything possible to minimise any inconvenience to you. If you have any questions, please call Technical Support at 0345 123 2229 or visit support.node4.co.uk. While it is important for Node4 to perform maintenance such as this to ensure the quality of our services, we do everything possible to minimise any inconvenience to our customers. We appreciate your patience and welcome any feedback. Kind regards, Node4 Technical Support
