We have scheduled maintenance for IOTDCS-2252 - SMSC STO Software Upgrade - Final VSS / Java version
Maintenance window: Start time of maintenance: September 3rd, 20:00 UTC
End time of maintenance: September 4th, 3:00 UTC
Impact: Enterprise impact: Service Affecting and Loss of Redundancy
Service Affecting and Loss of Redundancy
Please note that SMPP binds for SMSC accounts on the Central AMS SMSC will experience a brief disconnection of approximately 5 minutes, within the impact window of 21:00 UTC to 23:00 UTC on September 3rd.
This will result in a impact on SMPP binds on the Amsterdam SMSC. SMSC STO 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 STO SMSC prior to the scheduled activity to prevent any disruption to your traffic.
If binds are not moved to STO prior to the maintenance activity, they will be dropped from AMS, which will cause any SMSC traffic over those binds to fail.
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.
