Operations were mostly back to normal Friday morning at Denver International Airport after a technological outage hit airlines, banks and other vital institutions around the world.
The cause appears to be a botched security update by the cybersecurity company CrowdStrike that has affected Microsoft users worldwide, NPR reports.
Airline tracking service FlightAware reported more than 700 delays and 60 cancellations at DIA on Thursday night.
The number of delays stood at 538 as of 1:00 p.m. Friday, with another 105 flights canceled altogether.
“Operations have largely stabilized at DEN amid worldwide technology issues,” the airport posted on social media. “Airline ground stops have lifted at DEN — but delays are still impacting travelers. Please check with your airline directly before heading to the airport.”
The Regional Transportation District reported delays of up to 45 minutes across its light rail network early Friday as well because of a “communications failure,” affecting the E, H, R and W Lines.
The D Line is also suspended, with bus shuttles in place between Mineral Station and I-25 and Broadway station.
"RTD’s [Supervisory Control and Data Acquisition] servers continue to be impacted by the outage and are used to support rail operations and communications. Rail Operations is currently running a reduced number of light rail trains across the entire system due to the SCADA impacts. There are no current impacts to commuter rail services on the A, B, G, and N lines," RTD said in a midday press release.
Despite the light rail disruptions, commuter trains continue to operate on schedule. Bus routes have seen minimal delays, according to the agency.
RTD has no estimate for when the issue will be resolved. Its statement said the outage "has no impact on customer safety."
