Scheduled Maintenance
Telia IoTA Connectivity Services (DCS) IOTCHG-9386 - IOTDCS-2252 - SMSC STO Software Upgrade - Final VSS / Java version Sep 13, 2026 00:00-01:00 CEST
We have scheduled maintenance for IOTDCS-2252 - SMSC STO Software Upgrade - Final VSS / Java version
Maintenance window: Start time of maintenance: Postponed. A new implementation date will be communicated as soon as it becomes available (Was July 20th,15:00 UTC)
End time of maintenance: N/A (Was July 20th, 23:30 UTC)
Impact: Enterprise impact: Service Affecting and Loss of Redundancy
Please note that SMPP binds for SMSC accounts on the Central STO SMSC will experience a brief disconnection of approximately 30 minutes between 19:00 and 21:00 UTC.
This will result in a temporary 50% loss of redundancy for SMSC STO. SMSC AMS remains unaffected by this maintenance, and binds can be proactively migrated there to prevent any service disruption.
Action required for partners:
Please migrate your SMPP binds to the AMS SMSC prior to the scheduled activity to prevent any disruption to your traffic.
Customer action may be required during or after this maintenance.
Reason for maintenance: SW upgrade Central SMSC Software refresh
If you experience issues after the maintenance, please restart your device.
If you continue to experience issues please log an incident in your portal for IoT services.
We apologize for any inconvenience this may cause.

URGENT Maintenance window: Managed IoT Connectivity - Configuration Mobile | PS Core (Data) - Offload Oct 4, 2026 21:00 - Oct 5, 2026 02:00 CEST
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: 2026-10-04 21:00 CE(S)T
End time of maintenance: 2026-10-05 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.
