On 17 June 2017 at approximately 07:10 UTC,[1] AMC-9 experienced an anomaly on-orbit, the operator lost control and contact with the satellite, and it appeared to begin breaking apart.[5] SES claims that it re-established contact with the satellite on 1 July 2017, that it poses no risk of a collision with other active satellites, and that by the end of the day following the anomaly, most of AMC-9's traffic had been transferred to other SES satellites.[6][7]
