- As a user: Contact the company hosting your service, tell them that you value the security of your information.
- As a company: Send this page to your sysadmin or contact us to solve this for you.
- As a system administrator: Patch your OpenSSL and statically linked binaries; change your certificates, if you've been affected by this.
