Scheduled Maintenance

Planned work information: Managed IoT Connectivity - Configuration Mobile | PS Core (Data) - Offload Mar 22, 2026 21:00 - Mar 23, 2026 02:00 CET

Update - Due to upcoming restriction period this maintenance needs to be moved to 2026-03-15
Mar 06, 2026 - 14:16 CET
Scheduled - Dear User

We are sending this communication to inform you about a planned change activity.
CUSTOMER ACTION MAY BE REQUIRED

Work performed on: PS core - offloading traffic from one of the MMEs.

Traffic disturbance can occur due to this change. But for most customers is it not expected

Start time of maintenance: 2026-03-22 21:00 CE(S)T
End time of maintenance: 2026-03-23 02:00 CE(S)T
Enterprise disturbance time: 5h 00 min

Expected behavior: During the offload, devices are automatically requested by core node to reattach and connect to another node.

Enterprise impact: Traffic offload actions are performed before all PS Core upgrades and thus if customer has not earlier been affected by such action, they should not expect to get impacted this time either. Certain NB-IoT devices do not respond well to such offloads, and may need to be restarted to regain connectivity.

Worst case scenario:
Units stop communicating and needs a restart
If your devices haven't been affected before by offloading, you should expect no impact

Location of works:
Impacted Country: SE

Change reason:
Telia is doing a planned work in PS Core and for that is offloading traffic from one of the MMEs.
Changes of parameter settings with the purpose to optimize functionality or correct node or customer problems

If you experience problems after the change, please restart your device.
In case of any further problems, please log an incident in your portal for IoT services.

We are sorry for any inconvenience caused.

Best regards

CUSTOMER ACTION MAY BE REQUIRED

Work Performed On
Maintenance of the Telia IoT Connect platform authentication server.
This work is part of improving how customers log in and authenticate to our IoT Connect services.

Expected Impact
During the maintenance window:
Portal logins will be unavailable
Services requiring authentication may be temporarily inaccessible
The platform will be unable to display the online/offline status of SIMs, and their activity history will temporarily stop updating.
All ongoing IoT device traffic, SIM connectivity, and active sessions will continue to work normally.
No impact is expected on online traffic or device communication.
Traffic disturbance is limited only to authentication and portal access.

Maintenance Window
Start: 2026‑03‑17 14:00 CET
End: 2026‑03‑17 18:00 CET
Estimated downtime: ~4 hours
Enterprise disturbance time: During the full downtime
Enterprise impact: Customers cannot log in to portals; authentication-dependent services may be unavailable, online/offline status of SIMs, and their activity history will temporarily stop updating.
Worst case scenario: Extended login unavailability until the authentication service is restarted

Location of Works
Telia IoT Connect backend systems (authentication service).
Impacted Countries
SE

Reason for Change
Update and improve the authentication system to support a new login flow, enhanced security, and integration with Telia’s identity management service.
