Snapchat experienced a major outage on October 20, 2025, primarily due to a widespread Amazon Web Services (AWS) disruption affecting many online platforms. AWS confirmed the root cause was a domain name system (DNS) issue that affected their US-EAST-1 region, impacting services dependent on their cloud infrastructure, including Snapchat. AWS began implementing solutions early on October 20 and reported signs of recovery by mid-morning, but full resolution took time due to network propagation and backlog processing. As of October 20, the outage had been "fully mitigated," but ongoing intermittent disruptions were expected to continue for the rest of the day as the internet propagated these fixes. Therefore, Snapchat was expected to be fixed during the day on October 20, though exact timing for all users varied due to the nature of the recovery process. It is now October 21, so Snapchat should be nearly or fully restored, unless isolated issues persist in some regions. Users are advised to retry access and check for updates from Snapchat or AWS if problems continue.

In summary, Snapchat was fixed progressively throughout October 20 after AWS addressed the outage issues, and by your query time on October 21, Snapchat should be operational for most users.
