Linux Screens Join Windows Failures in Heathrow Information Display Outage

Linux-based information screens at London Heathrow have stopped working, following an earlier failure of Windows-based displays at the airport. The Register's report is brief and does not give a cause, duration, or recovery timeline.

Why it matters: Operators of public-facing digital signage should note that a failure spread across two operating systems points to a shared dependency, such as a network, identity, or content-management service, rather than a single OS defect.
