We have scheduled maintenance for IOTDCS-2252 - SMSC STO Software Upgrade - Final VSS / Java version
Maintenance window: Start time of maintenance: July 20th,15:00 UTC
End time of maintenance: 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.
