Snapchat experienced a significant outage on October 20, 2025, which affected millions of users, primarily due to an issue with Amazon Web Services (AWS) that Snapchat relies on for hosting. The problem involved Amazon's DNS system and was reported to be fully mitigated by AWS, though some disruptions were expected to persist throughout the day as systems caught up with backlog operations. At the time of the most recent updates on October 20, Snapchat was actively working on restoring full service, and the number of reports of issues had started to decline, indicating recovery was underway but not yet complete. The app's full functionality is likely to be restored later on October 20, 2025, as AWS resolution propagates globally and any lingering issues are cleared.

In summary, Snapchat's outage on October 20, 2025, was tied directly to AWS infrastructure problems, which have since been addressed by Amazon, and Snapchat service should resume fully on the same day as progress continues throughout October 20, 2025.
