In collaboration with our internet service provider, planned network maintenance activities will be performed to further enhance the resilience of our connectivity infrastructure. The implementation activities will be carried out by our infrastructure partner, while LINK Mobility teams will actively monitor, validate, and coordinate all activities throughout the maintenance window.
Maintenance Window
07 September 2026, 00:00 – 04:00 CEST
What is being done?
Following the incident experienced in June 2026, our infrastructure partner will perform corrective activities designed to restore the intended active-active routing configuration and validate automated failover capabilities across redundant network paths. LINK Mobility engineering and operations teams will monitor the activity and verify the results throughout the maintenance window.
Affected Services
The following services may be affected during the maintenance window:
- API n-eu.linkmobility.io
- API c-eu.linkmobility.io
- API s-eu.linkmobility.io
Potential Impact
No prolonged service interruption is expected. However, during routing failover tests, customers may experience brief connectivity disruptions, increased latency, or temporary interruptions while network traffic converges between redundant network paths. Any impact is expected to be short-lived.
Mitigation Measures
- Dedicated engineering teams from both organizations will monitor the environment throughout the activity.
- Continuous validation and testing will be performed during each implementation phase.
- LINK Mobility Service Monitoring and Incident Response teams will be actively engaged for the duration of the maintenance window.
- Communication channels between LINK Mobility and the infrastructure provider will remain active throughout the activity to ensure rapid response to any issues identified.
- The endpoint wsx.sp247.net will remain fully operational throughout the maintenance window and can be used as an alternative endpoint if required.
We will provide updates throughout the maintenance window and confirm once all activities have been successfully completed.
If you have any questions, please contact your local support department.
