During the impacted window, some users were unable to login, send documents for signature, sign documents, or perform other related functions in the web user interface. Actions performed using the API were unaffected.
Between 2025-03-19 03:16 AM UTC and 2025-03-19 08:32 AM UTC the Docusign entry gateway was the target of a Denial of Service Attack. The attack overwhelmed our application servers, consuming all resources and preventing normal application traffic from being processed.
Although users were unable to access the site during the attack, there is no indication that this event involved any data loss or corruption.
To mitigate impact and restore service, we implemented temporary rate limits.
