Multiple Computer Failures on the ISS

The main computer on the International Space Station failed early Sunday, and subsequent multiple computer anomalies prompted communication blackouts. The one main computer has two backup systems, and NASA reported that the three command & control computers are switching between prime, backup and standby. A software issue is suspected, and diagnosis continues. The computer system is critical to all aspects of space station operation.
NASA reported that despite the computer issues, all ISS systems are performing normally and there are no concerns for the safety of the crew.

The ISS computer is working again. Any 1 of the 3 computers can be the primary. There always is a "hot" backup & the third is in standby. (about 1 hour ago)

A "command & control" computer failed on ISS around 9a ET causing a brief loss of communications. A backup computer kicked in & all is well. (about 1 hour ago)
