Since we have identified you as an admin of a Salesforce org, we want to notify you of a change that may impact your Salesforce experience.
Salesforce is deploying an infrastructure feature called DNS Security, or DNSSEC, to add an extra layer of protection to our applications. On March 20, the first deployment of DNSSEC will be added to Salesforce Communities and then to other Salesforce applications in the future.
DNSSEC refers to Domain Name Service Security which is a set of protocols that adds a layer of trust to the domain name system (DNS) lookup and exchange processes. This ensures that you are connecting to the DNS records that belong to the real domain name you are trying to reach instead of a potentially fraudulent third-party site. For more information, please review the DNSSEC Knowledge Article.
On March 20, DNSSEC will be added to Salesforce Communities, and then to other Salesforce applications in the future, over the course of several months. Please review the DNSSEC Knowledge Article which has additional timeline details.
If you are unsure about whether you will be impacted by this change, check your connection here by entering https://internet.nl/test-connection into your browser. Be sure you are connected to your intranet or VPN before beginning the test. Otherwise, no other actions are required.
For most customers, this will be transparent. The protection granted by DNSSEC adds a new layer of trust. Certain U.S. Government Agencies have DNSSEC compliance mandates, for customers with this requirement, the change supports this.
