Transport providers, businesses and governments on Saturday are rushing to get all their systems back online after long disruptions following a widespread technology outage.
The biggest continuing effect has been on air travel. Carriers canceled thousands of flights on Friday and now have many of their planes and crews in the wrong place, while airports facing continued problems with checking in and security.
At the heart of the massive disruption is CrowdStrike, a cybersecurity firm that provides software to scores of companies worldwide. The company says the problem occurred when it deployed a faulty update to computers running Microsoft Windows, noting that the issue behind the outage was not a security incident or cyberattack.
Here’s the Latest:
LONDON — Britain’s travel and transport industries are struggling to get back on schedule after the global security outage with airline passengers facing cancellations and delays on the first day of summer holidays for many school pupils.
Gatwick Airport said “a majority” of scheduled flights were expected to take off. Manchester Airport said passengers were being checked in manually and there could be last-minute cancellations.
The Port of Dover said it was seeing an influx of displaced air passengers, with hourlong waits to enter the port to catch ferries to France.
Meanwhile, Britain’s National Cyber Security Center warned people and businesses to be on the lookout for phishing attempts as “opportunistic malicious actors” try to take advantage of the outage.
The National Cyber Security Center’s former head, 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 spotted quite quickly and essentially it was turned off.”
He told Sky News that some businesses would be able to get back to normal very quickly, but for sectors such as aviation it would take longer.
“If you’re in aviation, you’ve got people, planes and staffs all stranded in the wrong place… So we are looking at days. I’d be surprised if we’re looking at weeks.”
BERLIN — Eurowings, a budget subsidiary of Lufthansa, said it expected to return to “largely scheduled” flight operations on Saturday.
On Friday, the global IT outage had forced the airline to cancel about 20% of its flights, mostly on domestic routes. Passengers were asked to take trains instead.
“Online check-in, check-in at the airport, boarding processes, booking and rebooking flights are all possible again,” the airline said Saturday on X. “However, due to the considerable extent of the global IT disruption there may still be isolated disruptions” for passengers, it said.
DALLAS — Delta Air Lines and its regional affiliates canceled more than a quarter of their schedule on the East Coast by midafternoon Friday, aviation data provider Cirium said.
More than 1,100 flights for Delta and its affiliates have been canceled.
United and United Express had canceled more than 500 flights, or 12% of their schedule, and American Airlines’ network had canceled 450 flights, 7.5% of its schedule.
Southwest and Alaska do not use the CrowdStrike software that led to the global internet outages and had canceled fewer than a half-dozen flights each.
PORTLAND, Ore. — Mayor Ted Wheeler declared an emergency Friday after more than half of the city’s computer systems were affected by the global internet outage.
Wheeler said during a news conference that while emergency services calls weren’t interrupted, dispatchers were having to manually track 911 calls with pen and paper for a few hours. He said 266 of the city’s 487 computer systems were affected.
