You'd think NASA more than anyone would understand the price of not testing their software.

Evidently no -

"NASA lost contact with the space station at 9:45 a.m. ET, while the software on the station’s flight computers was being updated remotely from the ground by flight controllers in Houston, Texas, NASA reported in a release.


The outage is being blamed on a malfunction of the station’s data relay systems, which caused the space station’s main computer to bar communication with the satellites that allow it to communicate with NASA.

Communication was briefly restored around 11 a.m. ET as the space station flew over Russian ground stations. At that time, NASA told the space station’s crew to connect a backup computer to restore communications."
