All Day (Wednesday)


Event Details

On the 4th of October at 09:45 UTC during a GX/JX network activity, an incorrect configuration was transmitted to all GX/JX Aero terminals active at that time. At 10:50 UTC, the change was rolled back. However, all GX/JX Aero terminals active during this period were disconnected from the network and were not able to re-join. Maritime and Land GX was not affected.
In collaboration with the technology and terminal suppliers, a set of procedures to be executed on the impacted terminals was provided to the VARs to recover the terminal functionality.
In the meantime, a procedure to allow recovery Over the Air (OTA) was developed, tested and put in place on the 5th from 11:48 UTC. While effective for many of the impacted terminals, coordination and technical constraints outside of Inmarsat’s control prevented full geographic and timely implementation of this solution.
The vast majority of the impacted terminals have now been recovered using the local procedure and the Over the Air (OTA) solution. Direct communication with those VARs still affected by the issue are in place to ensure clear lines of communication and to expedite recovery.
Operational measures have been implemented to avoid similar incidents in the future.
