CrowdStrike to face US Congress over global IT outage

A CrowdStrike executive will testify at the US Congress on Tuesday to explain what caused the global IT outage on 19 July.

A rogue software update by the US cybersecurity company crippled up to eight and a half million computers using Microsoft systems around the world.

The outage meant GPs couldn't treat patients, people were stranded as planes couldn't get off the ground, and small businesses lost thousands in sales.
