Airports, ports, government agencies and private businesses in the Southland recovered Saturday from a massive global technology outage caused by a botched software update from cybersecurity firm CrowdStrike, causing what experts called the “largest IT outage in history.”

IT experts warned that it could take weeks for the global tech infrastructure to be fully restored after Friday’s botched software update crippled computer systems around the world.

“In some cases the fix can be applied very quickly,” Adam Leon Smith of BCS, the Chartered Institute for IT in England, told reporters. “But if computers have reacted in a way that causes them to go into blue screens … that can take days and weeks.”
