SEVERAL airports have gone old school after a global IT outage caused airport chaos. Images of whiteboards being used by staff at major airports have gone viral on X, formerly Twitter. Both Belfast International Airport and Manchester Airport have resorted to using whiteboards as they try to work around the tech issues. Meanwhile, schoolcomms - a communication app used by over 3,000 schools - says it is among the many companies affected by the outage. Cybersecurity software firm CrowdStrike say they have identified the issue behind the global outage as a flawed anti-viral update.
