LNDS is committed to keeping our data services secure, reliable, and up to date. This page explains how we manage updates and deployments, and when you might experience brief service interruptions.
We regularly deploy new features, apply security patches, and perform system maintenance on LNDS data services and platforms. Most updates occur seamlessly without service interruption. However, certain activities—such as major releases or system-level updates—may require a server reboot or application restart, which causes temporary downtime.
When service interruptions occur
In certain cases where an update requires a server reboot or application restart, some services may be temporarily unavailable. To minimise disruption, we schedule all such activities during non-office hours. Therefore, service interruption should only take place during the following times. If a service is temporarily unavailable during these hours, please try again shortly:
- Time: 5:00 PM to 8:00 AM (CET)
- Days: Monday through Friday
Your services remain fully available during standard office hours (8:00 AM to 5:00 PM CET).
Our update process
LNDS follows a three-phase approach for all deployments, releases, and maintenance activities:

Phase 1: Pre-checks
Before any update begins, we verify system readiness and data protection:
- Backup verification: We confirm that a complete and recent backup is available.
- Application validation: We verify that all applications are functioning correctly.
Phase 2: Update
We apply the relevant changes based on the activity type:
- Security updates: Latest security patches to address vulnerabilities and maintain compliance.
- Application deployments: New application versions with features, enhancements, bug fixes, and performance improvements.
- System maintenance: Server reboots and system-level updates for optimal performance.
Phase 3: Post-checks
We validate that all systems are operational:
- Operational verification: All applications have started correctly and are responding to requests.
- End-to-end validation: All services are functioning and communicating correctly.
If all checks pass, services return to full operation. If issues are detected, we immediately roll back to backup.
Why these activities matter
Regular updates, deployments, and maintenance:
- Deliver new features and capabilities
- Protect your data with the latest security patches
- Maintain system reliability and performance
- Ensure compliance with security and regulatory standards
We schedule all activities during non-office hours to minimise disruption to your work. If you have questions or experience unexpected interruptions, please contact our Service Desk.
