TerraStar Beam IOR Maintenance Notification
28 September 2023
There is a period of planned maintenance scheduled for Thursday 28th of September between 10:00 – 10:30 UTC temporarily affecting the TerraStar service availability on the IOR beam. Customers can expect a 15-minute service outage during the 30-minute maintenance period.
The maintenance is required to move IOR services to INMARSAT’S next-generation I-6F1 satellite. This new satellite is at 83.5E which will bring additional redundancy in the Asia-Pacific region. Upon completion of this maintenance, all TerraStar services on the IOR beam will be provided from the new I-6F1 satellite at the new location shown in red in the image below.

Refer to the mitigation section below for information on how to ensure seamless TerraStar, performance during this outage.
