Outage Infor­mation Inmarsat has recovered the I‑4 F1 satellite and restored services. However, with the complexity of the issue Inmarsat faced with the outage, it has not been possible to fully restore GSPS (satellite phone) services in the whole coverage area of the satellite.

Inmarsat is working hard on solutions and will provide an update on the likely timeframe for resto­ration as soon as they are able to do so. 

During the GSPS resolution period, Inmarsat will provide additional updates on times­cales as they finalise their resto­ration work.

Inmarsat appre­ciate that the delay in restoring GSPS services in the region is frust­rating for customers and sincerely apologise for this. 

We are working with Inmarsat to resolve the outage and will provide further updates when available.

We apologise for any incon­ve­nience this may cause.
