Snapchat experienced a significant outage on October 20, 2025, affecting millions of users worldwide. The issues were tied to a major internet outage at Amazon Web Services (AWS), which hosts much of Snapchat's infrastructure. This AWS outage originated in the US-EAST-1 Region (Northern Virginia) and caused Snapchat users to face problems like inability to log in, load or send messages, and account access issues such as temporary lockouts due to unusual activity detection. The service disruption was part of a broader impact affecting many other popular apps and websites relying on AWS. Snapchat acknowledged the problem and communicated to users that they were investigating and working on fixes. The core cause was related to network connectivity issues within AWS's internal systems, specifically involving their EC2 internal network and load balancers monitoring systems. While Snapchat itself did not provide detailed updates beyond recognition of the problem, the root cause was a significant AWS data center incident that cascaded into widespread service interruptions. In addition to this outage- related problem, users sometimes encounter Snapchat errors like "Something went wrong," which usually relate to internet connectivity issues, temporary server glitches, or app-specific bugs. These can sometimes be fixed by restarting the app, clearing the cache, or reinstalling the app, but during large-scale outages like this, fixes rely on Snapchat and AWS resolving the server issues. Therefore, as of October 20, 2025, the major problem with Snapchat is this large-scale service outage linked to the AWS infrastructure failure, causing widespread disruption in access and functionality for its users.
