This satellite experienced a power failure of several days in 2004 and returned to service with reduced capacity.[3]
In May 2011, Galaxy 27 was redeployed to 45.1° East longitude in order to expand Intelsat's services in the Middle East and Western Asia.[4] In October 2013, Intelsat moved the satellite to an inclined orbit at 66° East.[5] At its inclined orbit of 2.4° at 66° East, Galaxy 27 is in a collocated orbit with Intelsat 17.
