British Airways grounded all of its flights at London’s two biggest airports Saturday after an IT failure led to massive delays. BA CEO: “We believe the root cause was a power supply issue, and we have no evidence of any cyberattack” The outage was due to a power surge at a U.K.-based data center that began Saturday at 9:30 a.m. British Time. BA has apologized for the outages, delays, cancellations and overall disruption and promised to expedite refunds for anyone who could not travel.”]
