    X Spaces With Trump and Musk Is Off to a Glitchy Start

    by

    Elon Musk’s live conversation with former president Donald J. Trump on X got off to a glitchy start on Monday, a setback for the social media service as Mr. Musk pushes the company to regain its dominance as an online epicenter of political discourse.Some users who tried to listen to the conversation, which was hosted on the company’s audio livestreaming feature called Spaces, were greeted by silence and an error message that read: “Details not available.” Users said they had trouble accessing the livestream on desktop computers and mobile phones. Those who were able to get the livestream to work were met with hold music. The Spaces event was originally scheduled to start at 8 p.m. Eastern. The number of attendees fluctuated wildly as users struggled to gain access, drifting between 100,000 and more than 700,000 listeners. Mr. Musk blamed a cyberattack known as a distributed denial of service attack, or DDoS, for the glitches. DDoS attacks work by flooding servers with malicious traffic and knocking them offline. “Worst case, we will proceed with a smaller number of live listeners and post the conversation later,” he wrote. The attack could not immediately be verified.Mr. Musk claimed the system had been tested “with 8 million concurrent listeners” earlier that day.He had spent Sunday evening testing the service to make sure it could stay up and running by streaming himself playing a video game.

      Transportation Department to Investigate Delta After Flight Delays

      by

      Pete Buttigieg, the transportation secretary, made the announcement after the airline suspended travel for unaccompanied minors.Transportation Secretary Pete Buttigieg said on Tuesday that his department had opened an investigation into Delta Air Lines after the tech outage last week disrupted flights worldwide, and the agency wanted to hear from travelers who said that the airline had not complied with passenger protection requirements.The aim of the investigation is to “ensure the airline is following the law and taking care of its passengers during continued widespread disruptions,” Mr. Buttigieg said in a statement.“All airline passengers have the right to be treated fairly,” he added.The Transportation Department has consumer protection requirements that cover lost baggage, lengthy tarmac delays, compensation for being bumped from an overbooked flight and other protections.Passengers should try to resolve their travel issues directly with Delta, Mr. Buttigieg said, but the department wanted to hear from those who thought the airline “has not complied” with the protection requirements during the recent travel disruptions. His announcement included a link to a form for passengers to provide information about their concerns.Secretary of Transportation Pete Buttigieg said his agency wanted to hear from travelers who believed Delta Air Lines had not complied with federal protection requirements.Alex Welsh for The New York TimesDelta barred children under age 18 from traveling without a guardian as it struggled to recover from the global technology outage on Friday, which crippled Microsoft systems, hobbling train networks, disrupting hospitals and forcing airlines around the world to ground flights.The airline initially suspended travel for unaccompanied minors until Sunday, but then it extended the suspension through Tuesday. “Those already booked will not be able to travel,” Delta’s website said. “Please do not book new travel for unaccompanied minors during this time.”Delta has been the slowest U.S. airline to restore its operations, canceling more than 1,000 flights each day from Friday to Monday. Another 445 had been canceled as of 11 a.m. on Tuesday, according to the flight tracking website FlightAware. Some families said they had not been notified of the change until their children were turned away at the airline counter at the airport. More

      Congress Calls for Tech Outage Hearing to Grill Executive

      by

      The House Homeland Security Committee called on the chief executive of the cybersecurity firm CrowdStrike to testify on the disruption.A Congressional committee called on the chief executive of CrowdStrike to testify at a hearing about its role in a tech outage that roiled the global economy, in one of the first attempts to hold the cybersecurity company responsible.CrowdStrike sent a faulty security update to its customers Thursday night, resulting in millions of Microsoft Windows devices shutting down and disruptions to airlines, hospitals, logistics companies and others.Americans “deserve to know in detail how this incident happened and the mitigation steps CrowdStrike is taking,” wrote Representative Mark Green of Tennessee, the Republican chairman of the Homeland Security Committee, and Representative Andrew Garbarino, Republican of New York.The letter was sent to George Kurtz, CrowdStrike’s chief executive. Mr. Green and Mr. Garbarino asked the company for a response to scheduling the hearing this week, but did not specify when it would take place.“CrowdStrike is actively in contact with relevant congressional committees,” said a company spokeswoman. “Briefings and other engagement timelines may be disclosed at members’ discretion.”The request came as the world continued to deal with the fallout from the widespread outages. Delta Air Lines canceled more than 800 flights on Monday, leaving more passengers stranded. And other industries were still recovering after being knocked offline for hours.The outage underscores how the world has become reliant on a small group of companies to maintain its digital infrastructure. CrowdStrike, while little-known to most consumers, is the second largest American cybersecurity company. More than half of Fortune 500 companies use its products.“This incident demonstrates the interconnected nature of our broad ecosystem — global cloud providers, software platforms, security vendors and other software vendors, and customers,” said a Microsoft executive, David Weston, in a blog post on Saturday. “It’s also a reminder of how important it is for all of us across the tech ecosystem to prioritize operating with safe deployment and disaster recovery using the mechanisms that exist.”CrowdStrike’s products are used primarily by large businesses, not consumers. Its flawed update sent computers running Microsoft’s Windows operating system into a spiral where they continually rebooted. Although CrowdStrike sent a fix, many computers didn’t get it because of the loop. In many cases, businesses had to delete the damaging file from each machine manually.Mr. Kurtz on Friday told NBC’s “Today” show that the incident was not a cyberattack and was the result of the faulty update. But the congressional committee said in its letter to Mr. Kurtz on Monday said that the incident still presented vexing security questions.“Malicious cyber actors backed by nation-states, such as China and Russia, are watching our response to this incident closely,” the lawmakers said. “Protecting our critical infrastructure requires us to learn from this incident and ensure that it does not happen again.”Representative Ritchie Torres, Democrat of New York, on Friday also asked the Department of Homeland Security to investigate the outages.

      Flight Delays and Cancellations Continue Saturday but in Lower Numbers

      by

      An estimated 3,400 flights to, from and within the United States were canceled on Friday because of a tech outage. That made it the worst day of the year for flight cancellations.Airlines made progress toward containing the fallout from a tech outage that disrupted global travel on Friday, though some flight delays and cancellations extended into Saturday.In all, about 3,400 flights to, from and within the United States were canceled on Friday, according to FlightAware, a company that tracks flight information. That made it the worst day of the year for flight cancellations, beating Jan. 15 when airlines besieged by bad winter storms canceled nearly 3,200 flights in the United States.Delays and cancellations on Saturday appeared on track to be much lower than on Friday. Airlines had canceled a little more than 1,000 flights as of midday, with Delta Air Lines and United Airlines among the hardest hit, according to FlightAware.“Delta teams in airports, on board flights, on the phones and in messaging are working tirelessly to care for customers as the airline works to put flight crews and aircraft back in position following the disruption,” the airline said in a statement. Most of the flight cancellations on Saturday were concentrated in the morning and early afternoon, Delta said.Several carriers said they would waive fees and fare differences or offer refunds for affected passengers. The Transportation Department said that carriers may also have to compensate some travelers for food, lodging and transport.The outage on Friday was caused when CrowdStrike, a widely used cybersecurity provider, issued a flawed software update to Microsoft devices. Soon after, airlines and many other businesses and institutions began suffering technical failures. For airlines, a wide range of systems were affected, including those that calculate aircraft weight, check in customers, issue boarding passes and manage call center phone lines.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Is Your Flight Delayed by the Tech Outage? Here’s What You Need to Know.

      by

      While service is slowly recovering, flights have been delayed and canceled worldwide. Here’s information on the most affected airlines and airports, passengers’ rights and how to reach airline customer service.Travel plans across the world were thrown into disarray on Friday, as a global technology outage disrupted businesses and services — including air travel — leaving thousands of flights canceled or delayed across the United States and beyond.While service was slowly recovering by midmorning Eastern time, the ripple effect was still snarling travel plans as delayed and canceled flights created a buildup of passengers waiting at airports, and some planes and crews out of position.“The anxiety is getting up a little,” said Adonis Ajayi, 35, at Ronald Reagan Washington National Airport on Friday morning. Mr. Ajayi was on his way to Key West, Fla., for a long weekend and said he had been checking social media constantly for flight updates — his flight had been delayed for nearly three hours. “I’ve never seen anything of this scale.”The outage was caused by a flawed update from the cybersecurity firm CrowdStrike, whose software is used globally by scores of industries to protect Microsoft systems. Messages posted on social media by travelers worldwide showed flights grounded, some terminal monitors down and crowds of stranded passengers waiting at airport gates and customer service desks. Some passengers at one airport in India had to stand in long lines to obtain handwritten boarding passes.Which airports have been hit the worst?In the United States, Hartsfield-Jackson Atlanta International, the world’s busiest airport, appeared to have the most flights affected by the outage on Friday morning, with more than 230 incoming and outgoing flights canceled and more than 370 flights delayed, according to FlightAware, a real-time flight tracker.Many other airports, including hubs in New York, Chicago and Charlotte, N.C., also appeared to experience significant disruption.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      by

      A problem with Microsoft’s Azure system also hit check-in and booking systems at Allegiant and Sun Country Airlines.Frontier Airlines briefly grounded all flights on Thursday amid a major outage in Microsoft networks, which also knocked out some computer systems at low-cost carriers Allegiant Air and Sun Country Airlines.Microsoft said on the status page for Azure, its flagship cloud computing platform, that the problem began at 5:56 p.m. and affected multiple systems for customers in the central United States.“Our systems are currently impacted by a Microsoft outage, which is also affecting other companies. During this time booking, check-in, access to your boarding pass, and some flights may be impacted,” Frontier said in a post on X.The airline issued a ground stop for all its flights, according to a notice posted on the Federal Aviation Administration’s website. The ground stop was lifted about 35 minutes later.Airlines sometimes issue these orders to temporarily halt flights because of technical issues.Frontier did not specify how many flights and passengers have been affected so far. The Denver-based airline operates a fleet of more than 100 planes, according to its website.The Microsoft outage hit at least two other airlines.“One of our information vendors is experiencing a global outage affecting multiple airlines. As a result, some of our services are temporarily unavailable,” Sun Country said.Allegiant said on X that customers may face problems with check-ins, bookings and issuing boarding passes. More

      AT&T Offers $5 Credit After Widespread Service Outage

      by

      Thousands of customers lost service on Thursday when the telecommunications company ran into problems while trying to expand its network, the company’s chief executive said.AT&T will offer a $5 credit to customers affected by a widespread outage on Thursday that was caused by technical issues the company encountered while trying to expand its network, its chief executive said on Sunday.The outage, which started around 3:30 a.m. Eastern time, temporarily cut off connections for users across the United States.Some of the affected cities included Atlanta, Los Angeles and New York, according to Downdetector.com, which tracks user reports of telecommunication and internet disruptions.At its peak, the site had received about 70,000 reports of disrupted service for AT&T. Service was fully restored after about seven hours.“No matter the timing, one thing is clear — we let down many of our customers, including many of you and your families,” the chief executive of AT&T, John T. Stankey, wrote in a letter dated Sunday. “For that, we apologize.”In an effort to “make it right” AT&T is offering customers a $5 credit on their AT&T Wireless account, according to the company’s website.“For the portion of consumer and small business customers most impacted by the outage, we are automatically applying an account credit to compensate them for the inconvenience they experienced,” the company said.It will take one to two billing cycles for the credit to appear, depending on when a customer’s bill closes, the company said.Prepaid customers will have options available if they were affected, Mr. Stankey wrote, but did not specifically identify those options.AT&T also said it was “working closely” with Mid-Market and Enterprise customers, which are internet plans for businesses, to address their concerns.It was not immediately clear how much the credits would amount to in lost revenue. A company representative could not be reached on Sunday.In a statement, AT&T emphasized that the outage wasn’t caused by a cyberattack.“Our initial review of the cause of Thursday’s outage indicates it was due to the application and execution of an incorrect process used while working to expand our network,” Mr. Stankey wrote in his letter.The credit is meant to refund customers for the day that the service was lost, he wrote.“I believe that crediting those customers for essentially a full day of service is the right thing to do,” Mr. Stankey wrote.
