Recently there was an issue reported by Cloudflare that impacted their edge servers.

The issue in some cases involved surpassing the end of a buffer and returning memory that contained private information such as HTTP cookies, authentication tokens, HTTP POST bodies, and other sensitive information. Portions of this data may have been cached by search engines and therefore it’s recommended to change your passwords to any services hosted by Cloudflare.

DocuSign does not utilize Cloudflare in our Digital Transaction Management platform nor do we leverage this service for our corporate infrastructure.
