Snapchat experienced a major outage on October 20, 2025, which left millions of users worldwide unable to log in, send messages, or access many features of the app. This disruption was tied to a significant internet outage caused by problems at Amazon Web Services (AWS), the cloud infrastructure provider for Snapchat and many other apps. Specifically, AWS faced issues related to its domain name system (DNS), which translates web addresses into IP addresses, and also had problems with its DynamoDB database. Due to AWS's central role in internet infrastructure, this outage impacted not only Snapchat but also other popular platforms like Roblox, Fortnite, Canva, and several banks and financial services. Snapchat acknowledged the problem early and was actively working on resolution alongside AWS. Although AWS announced that the issue had been fully mitigated later on October 20, some residual service disruptions persisted throughout the day as the systems worked through backlogs. This outage was due to technical failures at AWS, not an issue intrinsic to Snapchat itself, and service resumed as AWS restored normal operations.
