(NEWSnet) — Transport providers, businesses and governments on Saturday are rushing to get all their systems back online after long disruptions following a widespread technology outage on Friday.

The biggest continuing effect has been on air travel as carriers canceled thousands of flights on Friday.

The long lines were among the most visible impacts of a technology outage related to a software update from cybersecurity firm CrowdStrike. The problem affected the ability of Microsoft computers to simply function. CrowdStrike said Friday it had identified the problem and was fixing it.

Here’s the Latest:

Flights canceled across the country

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, Oregon, mayor declares an emergency over the outage

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.

Border crossings into the US are delayed

People seeking to enter the U.S. from both the north and the south found that the border crossings were delayed by the internet outage.

The San Ysidro Port of Entry was gridlocked Friday morning with pedestrians waiting three hours to cross, according to the San Diego Union-Tribune.

Even cars with people approved for a U.S. Customers and Border Protection “Trusted Traveler” program for low-risk passengers waited up to 90 minutes.

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

Problems persist across Europe

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.

London's Gatwick Airport said “a majority” of scheduled flights were expected to take off Saturday.

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.

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.
