Microsoft 365 says it has completed its mitigation actions and its telemetry indicates all previously impacted Microsoft 365 apps and services have recovered.

“We’re entering a period of monitoring to ensure impact is fully resolved,” the company said.

The Maricopa County Elections Department in Arizona said the global IT outage is impacting some voting locations, as early voting in statewide primaries rolls out.

In a statement posted to X, the department directed voters to a web page to find out which polling places remain unaffected by the incident.

Early primary voting has been open for Grand Canyon states since July 3; Arizona's official primary election is Tuesday, July 30.

The state-level primaries will have a significant impact on the balance of power in the U.S. Senate and House: Former gubernatorial candidate Kari Lake is squaring off against Pinal County Sheriff Mark Lamb for the opportunity to face Democrat Ruben Gallego to replace outgoing Sen. Kyrsten Sinema.

Meanwhile, six Republicans — including former Senate candidate Blake Masters, are vying to replace retiring Republican Debbie Lesko in the state's 8th Congressional District.

Several major U.S. hospitals were forced to cancel surgeries and doctor’s appointments amid the global computer outage.

Hospital staffers in New York and Boston said they were unable to access some medical records or were having trouble figuring out where to send critically ill patients as several operating rooms had been shut down.

“Every day, we have a plan that’s mapped out really carefully so that we can plan our resources,” said one employee of an affected New York City hospital system. “That’s all blown up,” the staffer said, asking to not be identified because the person wasn’t authorized to speak on behalf of the health care system.

Microsoft CEO Satya Nadella released the company's first statement about the outage early Friday afternoon, saying: “CrowdStrike released an update that began impacting IT systems globally. We are aware of this issue and are working closely with CrowdStrike and across the industry to provide customers technical guidance and support to safely bring their systems back online.”

Journalists and Republicans leaving Milwaukee after this week's Republican National Convention may have a feeling of déjà vu if their travel plans are interrupted by this global outage.

It's the second in-person GOP convention in a row (2016 and 2024, since 2020 was largely virtual) that ended with a major transportation-related outage.

Southwest reported a "technology outage" on July 20, 2016, the second to last day of the convention in Cleveland. The company ultimately said more than 2,000 flights were delayed or cancelled. But while the outage happened midweek, travelers were still feeling some effects of it days later and this reporter had to drive colleagues with cancelled flights home from Cleveland.

Travelers stuck this morning at JFK Airport in New York met the delays with resignation, weariness and a need to hit the bar.

Colby Black, 45, took the delays in stride, even though he wasn’t sure when his rescheduled flight to Los Angeles would take off. It was originally set to depart at 6 a.m.

“I’m just tired. I want to sleep,” said Black, who woke up at 3 a.m. “But otherwise, yeah, it happens.”

One mother said she hadn’t slept the night before, just so she and her infant son could get to JFK on time.

“I’m still up, running on no sleep,” she said as she was seated on a barstool beside a heavy pour of chilled white wine. She wasn’t originally planning to order a preflight drink.

“Hell no. I got to the airport at 4 o'clock this morning,” she said.

Video from the airline tracker Flightradar24 shows how U.S. air travel was scaled back dramatically in the early morning hours, as airlines and airports scrambled to deal with IT issues related to a security bug.

An image that has instilled panic in computer users for decades popped up on screens worldwide today: the dreaded “Blue Screen of Death.”

Appearing everywhere from Macy’s flagship store in New York City to airports in India, the Blue Screen of Death has long prompted groans and frantic questions of “Did my work save?” It’s a Microsoft Windows error screen indicative of a system crash — meaning a computer issue has resulted in the operating system no longer being able to run safely.

An unwanted sight that has become so widely known over its more than 30-year existence, it’s sometimes referred to by its acronym, BSoD. Today, the blue screen taunted millions globally amid a widespread technology outage that halted flights, knocked broadcasters off the air and disconnected some emergency phone lines. Texas-based cybersecurity firm CrowdStrike said early today that the outage was the result of a “defect found in a single content update for Windows hosts,” not a cyberattack, and that a fix had been deployed.

CrowdStrike CEO George Kurtz released an updated statement on X, assuring customers that this was not a "security or cyber incident," and that their information is still protected.

"We are working with all impacted customers to ensure that systems are back up and they can deliver the services their customers are counting on," Kurtz added.

He said that he would provide updates via his X account, LinkedIn and the CrowdStrike website.
