The primary computer that controls critical station functions defaulted to a backup computer, but it was not letting the station communicate with NASA's Tracking and Data Relay Satellites, the said.

Officials in Houston were later able to communicate briefly with the crew as the space station flew over Russian ground stations. They instructed them to connect a backup computer to begin the process of restoring communications.

And communications were restored nearly three hours after the initial breakdown, NASA said in a .
