Snapchat experienced a major outage starting in the early morning hours of October 20, 2025, caused by a widespread Amazon Web Services (AWS) disruption primarily affecting the US-EAST-1 AWS region. The outage led to millions of users being unable to log in, send messages, or access their accounts, with error messages about temporary account disablement due to unusual activity. Reports peaked at over 22,000 users affected early that morning. Amazon resolved the root cause, related to internal network and DNS issues, but the recovery process involved clearing a backlog of requests, meaning service disruptions persisted throughout the day. Downdetector data showed a decline in issue reports from 22,000 to about 10,000 by around 9:00 a.m. ET on October 20, but some users still faced problems hours later. Given that the outage started around 3 a.m. ET and continued with some disruptions reported well into the day, Snapchat's downtime on October 20 was significant, likely lasting most of the day with gradual restoration of service as AWS systems recovered fully. Users were advised to be patient as full resolution took several hours to propagate across the internet. In summary, Snapchat was down for approximately most of October 20, 2025, due to AWS infrastructure failure, with phased recovery ongoing but some lingering effects still possible later that day.
