Latest technical glitch | Airlines scramble to get back on track after global technical disruption

At the heart of the massive outage is CrowdStrike, a cybersecurity firm that provides software to dozens of companies worldwide. The company says the problem arose when it deployed a faulty update to computers running Microsoft Windows, and notes that the issue behind the outage was not a security incident or cyberattack.

LONDON — Britain’s travel and transport sector is struggling to get back on track after the global security outage left air passengers facing cancellations and delays on the first day of the summer holidays for many schoolchildren.

Gatwick Airport said “a majority” of scheduled flights would depart. Manchester Airport said passengers were being checked in manually and there could be last-minute cancellations.

The Port of Dover reported an influx of displaced air passengers and that passengers had to wait for hours to enter the port and take the ferry to France.

Meanwhile, the UK’s National Cyber ​​Security Centre warned people and businesses to be wary of phishing attempts as “opportunistic malicious actors” attempt to take advantage of the outage.

Former National Cyber ​​Security Centre director Ciaran Martin said the worst of the crisis was over, “because the nature of the crisis is that it went very wrong very quickly. It was picked up quite quickly and in effect it was shut down.”

He told Sky News that some businesses could return to normal very quickly, but that it would take longer for sectors such as aviation.

“When you’re in aviation, you have people, planes, personnel all stranded in the wrong place… So we’re looking at days. I’d be surprised if we were looking at weeks.”

BERLIN — Eurowings, a budget subsidiary of Lufthansa, said it expected to resume “largely scheduled” flights on Saturday.

On Friday, the global IT outage forced the airline to cancel about 20% of its flights, mainly on domestic routes, and passengers were asked to take the train instead.

“Online check-in, airport check-in, boarding processes, booking and rebooking of flights are all possible again,” the airline said on Saturday at X. “However, due to the significant scale of the global IT outage, there may still be isolated disruptions” for passengers, it said.

DALLAS — Delta Air Lines and its regional subsidiaries canceled more than a quarter of their East Coast flight schedules Friday afternoon, according to aviation data provider Cirium.

More than 1,100 flights operated by Delta and its subsidiaries have been canceled.

United and United Express had more than 500 flights canceled, or 12% of their schedules, and American Airlines’ network had 450 flights canceled, or 7.5% of their schedules.

Southwest and Alaska are not using the CrowdStrike software that was responsible for the global internet outage. Fewer than six flights were canceled each.

PORTLAND, Ore. — Mayor Ted Wheeler declared a state of emergency Friday after more than half of the city’s computer systems were affected by the global internet outage.

Wheeler said at a news conference that while emergency calls were not interrupted, dispatchers had to manually monitor 911 calls for several hours with pen and paper. He said 266 of the city’s 487 computer systems were affected.

SAN DIEGO — People trying to enter the U.S. from both the north and south experienced delays at border crossings due to the internet outage.

According to the San Diego Union-Tribune, the San Ysidro Port was completely jammed Friday morning, with pedestrians having to wait three hours to cross.

Even cars with people approved for a U.S. Customers and Border Protection “Trusted Traveler” program for low-risk passengers faced waits of up to 90 minutes. The program, known as SENTRI, allows passengers to go through customs and passport control faster if they make an appointment for an interview and undergo a background check to speed up their passage through customs and passport control once they arrive in the U.S.

Meanwhile, at the U.S.-Canada border, Windsor police reported long delays at border crossings at the Ambassador Bridge and the Detroit-Windsor Tunnel.
