Outage Infor­mation Inmarsat are experi­encing a full service outage on their Inmarsat I‑4 F1 Satellite. 

Inmarsat have advised that this is being treated as a top priority with key technical resources involved. 

Due to the nature of the problem and the complexity of the recovery procedure, Inmarsat expect this to be an extended outage.

Inmarsat engineers have entered into recovery proce­dures to restore services on the Inmarsat I‑4 F1 Satellite, these proce­dures are ongoing. Classic Aero has been fully restored, and the transition of Inmarsat‑C from the contin­gency network back to 4F1 is in progress. 

We expect a further update from Inmarsat 18th April 2023 at 21:00 UTC.

We will continue to provide further updates as soon as further infor­mation related to the resolution of the outage is provided.

We apologise for any incon­ve­nience this may cause.
