Microsoft said an outage of Azure cloud applications was triggered by a distributed-denial-of-service cyberattack.<\/p>\n\n\n\n
The DDoS attack began early Tuesday and an error in Microsoft\u2019s automated protection mechanisms worsened the impact rather than mitigating it, the company said in a status update<\/a>.<\/p>\n\n\n\n Customers were affected in multiple regions, including services running on Azure. <\/p>\n\n\n\n For example, mobile ordering at Starbucks Corp. was disabled for hours because of the issues affecting Azure, according to a person familiar with the matter.<\/p>\n\n\n\n Denial-of-service attacks direct internet traffic at a website in mass volume to disrupt it or shut it down. <\/p>\n\n\n\n The incidents have become a\u00a0persistent annoyance\u00a0for financial institutions, causing intermittent downtime and forcing security staffers to repel the activity.<\/p>\n\n\n\n Reports of outages on Azure and Microsoft 365 began to spike shortly after 7 a.m. in New York and comprised hundreds of complaints at the incident\u2019s peak, according to user reports compiled<\/a> by Downdetector. <\/p>\n\n\n\n Microsoft said the incident was fixed by about 5 p.m. in New York. <\/p>\n\n\n\n The issue also affected multiple Microsoft 365 services and features, Microsoft said in a post on social network X<\/a>. Microsoft 365 includes common productivity applications like Outlook, Word and Excel.<\/p>\n\n\n\n Mobile ordering for Starbucks had largely been restored by about 1 p.m. in New York.<\/p>\n\n\n\n The company was working to address limited interruptions that continued, a Starbucks spokesperson said.<\/p>\n\n\n\n Earlier this month, some 8 million computers running on the Windows operating system crashed after the cybersecurity firm CrowdStrike Holdings released a flawed software update. <\/p>\n\n\n\n In addition, Microsoft has also been grappling with the fallout from a series of cyberattacks that prompted the US government to issue a scathing report calling for companywide changes.<\/p>\n\n\n\n
