Overview of Virtual Appliance Updates

New virtual appliance (VAs) software versions become available automatically and are usually applied without any intervention required. To ensure the high availability of DNS services, you must have two VAs running for automatic updates to take place.

Both the connector and the VA are capable of automatic updates. To download updates, these components require access to the following URLs:

443 (TCP) to disthost.opendns.com
443 (TCP) to disthost.umbrella.com

If you would like to find out more about upcoming versions, including release notes, see Service Updates. Click Follow to receive update notifications.
