Microsoft-CrowdStrike issue causes ‘largest IT outage in history’

FTC Chair Lina Khan weighed in on the ongoing CrowdStrike outage in a series of posts on X on Friday. Without mentioning CrowdStrike or Microsoft, she appeared to blame the outage on concentrated market power, which creates “fragile systems,” she wrote.

“Concentrating production can concentrate risk, so that a single natural disaster or disruption has cascading effects,” Khan wrote in the series of posts.

Khan did not announce an FTC investigation of the incident, but she linked to unrelated past actions she has taken, including opening up a query on cloud computing companies, and seeking public comment on companies that frequently buy smaller competitors, like in the technology industry.

Some Amazon warehouses in the U.S. were grappling with disruptions set off by the global IT outage.

Three Amazon warehouse staffers said the outage took down an app used by employees to manage their schedules and submit time off requests, called A to Z, early Friday morning, though it has since been restored in some areas. The employees asked to remain anonymous because they weren’t authorized to speak publicly about the situation.

The outage also disrupted some Amazon employees’ ability to access an internal service called “Anytime Pay,” which allows staffers to withdraw earnings before their next paycheck. “Anytime Pay is unavailable due to a global outage impacting users to access internal IT services,” according to a notice on Amazon’s internal payroll site for warehouse staffers, which was viewed by CNBC.

At some sites, operations were briefly halted. An Amazon warehouse worker in South Carolina, who asked to remain anonymous, said their site passed the time by performing karaoke in exchange for “cola cash,” or credits that can be used to purchase snacks and drinks at the facility.

The disruptions also touched Amazon’s trucking operations. Truck drivers who use Relay, a platform that lets them book jobs moving Amazon cargo, said they were briefly unable to pick up loads at Amazon warehouses due to system issues.

“Everything was bluescreened,” said Dwight Evitt, a truck driver in San Marcos, Texas.

Representatives from Amazon didn’t respond to requests for comment.

CrowdStrike CEO George Kurtz apologized in a blog post for the global outage Friday and reiterated that his company is working closely with impacted customers and partners to restore all systems.

Kurtz encouraged customers to “remain vigilant” in ensuring they engage with official CrowdStrike representatives as they seek support.

“We know that adversaries and bad actors will try to exploit events like this,” he wrote.

He added that the company’s blog and technical support portal will remain the official channels for updates.

Kurtz reiterated the outage was caused by a defect in a Falcon content update for Windows hosts, and Mac and Linux hosts were not impacted. He emphasized again that the outage was not caused by a security breach or cyberattack.

“As we resolve this incident, you have my commitment to provide full transparency on how this occurred and steps we’re taking to prevent anything like this from happening again,” he wrote.

At CommonSpirit Health, which provides care across 150 hospitals in 24 states, employees noticed that many of the health systems’ desktop computers were displaying a blue error screen in the early hours of Friday morning.

The health system has tens of thousands of computers, and they serve as a “window” into all of the organization’s other systems, Daniel Barchi, CIO at CommonSpirit, told CNBC.

“It’s the way our physicians who are doing surgery have access to the images that have been made on a patient’s MRI,” Barchi said. “It’s the way the nurse knows which drugs to give to the patient.”

Barchi said the disruption was deemed a “priority one event,” and that he and other senior IT leaders began working to identify the issue around 2 a.m. They determined the problem was related to an update that CrowdStrike had pushed out, and they were able to contain it before it had finished rolling out to all the computers within CommonSpirit.

But though some computers remained operational, the compromised computers must be fixed manually, one by one.

“We were all stunned by the fact that if a computer gets this blue screen lock up, there’s no way to push a software patch to fix it,” he said. “You literally have to go up to it, login as an administrator, a technology person, and then delete a line of code and make that enabled to come back online.”

Barchi said CommonSpirit has managed to bring many of its computers back online, and many hospitals are returning to business as usual. The health system will continue its remediation process and work to fix its servers through the rest of the day, he said.

Electric vehicle maker Tesla temporarily halted production on lines at some of its manufacturing facilities on Friday after an unprecedented IT outage impacted global operations due to system issues at cybersecurity firm CrowdStrike.

According to correspondence obtained by CNBC, Tesla’s IT teams notified employees that there was a “windows host outage,” and different systems were affected including “servers, laptops and manufacturing devices.” The IT teams informed Tesla employees that they may see a “blue screen” on their various devices.

Tesla CEO Elon Musk, who also owns social media platform X, posted several complaints about the CrowdStrike outages to his account, which has more than 190 million followers, throughout the morning.

Two Tesla employees who spoke with CNBC, but asked to remain unnamed because they were not authorized to speak on behalf of the company, said that some manufacturing lines were slow to start on Friday morning, and others were temporarily halted in California and Nevada. They also said managers were telling some workers to prepare for canceled shifts or to go home early.

Business Insider, which first reported on the IT memo, wrote that workers in Tesla’s Texas vehicle assembly plant were sent home overnight in response to the outages as well.

As a key Tesla vendor, Microsoft, scrambled to restore its apps and services Friday morning, CEO Satya Nadella wrote in a statement on X that an update from CrowdStrike on Thursday impacted global IT systems.

In replies to Nadella on X, Musk wrote that the outages had caused a “seizure” to the automotive supply chain, adding, “We just deleted CrowdStrike from all our systems, so no rollouts at all.”

Employees confirmed that Tesla was using CrowdStrike as of Friday.

Tesla shares were down more than 3% in afternoon trading on Friday. Tesla did not immediately respond to a request for further information.

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.

The health-care software vendor Epic Systems, which houses more than 305 million patient medical records, said the outage has caused technical issues that are preventing some health-care organizations from using its systems. 

An Epic spokesperson said the disruption is not affecting the company’s services directly, but it has received reports that the laptop and desktop workstations that some groups use to access Epic are down. Additionally, some groups have reported problems with their data center software, which means they are unable to access patient records through Epic.

“Organizations that have been affected are following pre-established downtime protocols to continue delivering patient care,” an Epic spokesperson told CNBC in a statement. “Epic staff are working with customer IT teams to restore access as fixes or mitigation approaches are available from CrowdStrike.”

Epic said its platform for cloud-based applications called Nebula was impacted by the outage. Features like its telehealth offering were temporarily unavailable, but Epic said access has been restored. Epic is continuing to monitor Nebula, the company added.

Secretary of Transportation Pete Buttigieg said Friday on CNBC’s “Squawk on the Street” that he expects the transportation delays to be smoothed out and “resembling normal” by Saturday.

“The issue has been identified. It’s really a matter of the kind of ripple or cascade effects as they get everything in their networks back to normal,” Buttigieg said. “These flights, they run so tightly, so back-to-back that even after a root cause is addressed, you can still be feeling those impacts throughout the day.”

Buttigieg added that there is no indication on any impact to the Department of Transportation’s own systems including air control, but that he is expecting more issues on the airlines’ side.

“We’re tracking all of the various impacts hitting different forms of transportation. The one that I think most people are likely to experience directly is those airline cancellations and delays if you’re planning to fly today,” Buttigieg said.

Nearly 28,000 flights had been delayed globally as of about 11 a.m. ET Friday, with roughly 4,700 of those delays within, into or out of the United States, according to FlightAware data. More than 2,950 flights have been cancelled, with almost 1,800 of them U.S. flights.

CrowdStrike CEO George Kurtz apologised Friday for the systems update that caused a global IT outage, telling NBC “we’re deeply sorry.”

Businesses are still reeling, with many flights grounded and payments systems downed after the cybersecurity giant’s antivirus software update went awry.

“The system was sent an update, and that update had a software bug in it and caused an issue with the Microsoft operating system,” he told NBC’s “Today”.

The CEO reiterated that it was not a security incident or cyberattack, and that the company is working with customers to get them back online.

He said the update was normal and part of the firm’s routine process to prevent security risks. However, he noted that a thorough investigation would need to be carried out into what went wrong.

“We have to go back and see what happened here. But if there’s a negative interaction with the way some of these operating systems work — in this particular case, it was, it was only a Microsoft operating system that was impacted — you’ll see a reaction like this,” he said.

The ongoing global IT outage might not have an “incredibly straightforward” fix, according to Tom Lysemose Hansen, Chief Technology Officer at Norwegian cybersecurity company Promon.

“Crowdstrike’s affected customers will have to effectively break into their own systems to get everything back online by logging into the admin console and booting their systems in safe mode,” he said in emailed comments.

He added that CrowdStrike underpins the everyday operations of many organizations, “being present in anything from point of sale to ATMs as well as being used on Microsoft Windows systems.”

CrowdStrike earlier on Friday said it was applying a fix to an identified and isolated defect in a single-content update for Windows hosts. The company did not immediately disclose what this measure would entail.

The global IT outage is having a “profound impact,” and nothing similar has ever been seen before, Satnam Narang, senior staff researcher at cybersecurity firm Tenable, told CNBC on Friday.

“It’s very far reaching and we’re still just in the beginnings of this right now,” he said. Attempts to resolve the issue would take time, according to Narang.

“The challenge here is that security software — because it’s doing its job to protect organizations — it has to have more privileged access to these machines. So ... while people may be seeing these as Windows failures, they’re looking at it and seeing a little blue screen pop up, it’s not actually a Windows issue, it’s related to a faulty or bad update from those security software,” he explained.

“We’ve never seen anything like this before, it’s very unprecedented.”

Speaking to CNBC from a hospital, Narang said health care was one of the key areas that has been impacted.

“Systems are offline which means, you know, patient records cant be accessed and medication can’t be administered properly to patients,” he said.
