Snapchat experienced a major outage starting in the early morning hours of October 20, 2025, affecting millions of users who were unable to log in, send messages, or access features. The disruption was caused by a significant outage at Amazon Web Services (AWS), a cloud platform that hosts Snapchat and many other major websites and applications. The issue was traced to an internal network connectivity problem in AWS's US-EAST-1 region in Northern Virginia, affecting many services across the internet simultaneously, including other platforms like Reddit, Roblox, Fortnite, and various banks. Amazon quickly investigated and announced that the root DNS-related problem was "fully mitigated," but some users continued to face issues due to AWS working through a backlog of requests and propagation delays in fixing the problem globally. Snapchat acknowledged the issues and has been working with AWS on a fix, but the restoration took several hours with fluctuating service availability throughout the day. This outage highlighted the risks of heavy reliance on a single cloud provider for critical internet services, with experts noting the widespread impact of such failures on social media, financial institutions, gaming, and more. By later in the day, systems were mostly restored, but some disruptions lingered as AWS fully resolved the technical problems. In summary, the ongoing situation with Snapchat is directly linked to the large-scale AWS outage on October 20, 2025, causing temporary but widespread service interruptions. Users were advised to "hang tight" as Snapchat and AWS worked on restoring full functionality.
