DNS resolver services perform updates in a serial format, where service points and DNS
resolver services on Fleet Service Points will update one by one. During the DNS resolver
service update, they will continue to process query information, resulting in no
When the DNS resolver service version of a site is updated as a result of an automatic
update across all sites or a manual update of selected sites, the service points with
DNS resolver service built in that are deployed from those sites recognize that an
update is available on the next periodic poll to the DNS Edge Cloud. The DNS resolver
service on the service point then retrieves the update from the DNS Edge Cloud and
serially begin to perform an update to the new DNS resolver service version.
resolver services deployed on Fleet Service Points do not periodically poll the DNS Edge
Cloud for updates. To update the DNS resolver service deployed on Fleet Service Points,
you must perform a manual update from the Sites
The DNS resolver service update settings allow you to control whether DNS resolver services are automatically updated with each new DNS resolver service version release.
By default, DNS resolver services are configured to automatically update.
If you disable automatic DNS resolver service updates, all DNS resolver services will
remain at their current DNS resolver service version and must be updated manually
through each site. With this capability, you can update DNS resolver services associated
to a test site to verify that the newer DNS resolver service updates don't break
existing functionality before rolling out the update to the rest of your organization.
You also have greater flexibility to roll out DNS resolver service updates during a
controlled maintenance window.
DNS resolver services that operate on older versions
of software might not be able to consume the latest features available in the DNS
Edge Cloud. By default, the DNS Edge Cloud will continue to support at least two DNS resolver service versions. BlueCat will notify you when DNS resolver service
versions are going out of support to ensure that you have time to validate the
latest DNS resolver service versions.
If your DNS resolver service version falls
outside of the supported DNS resolver service versions, your DNS resolver service might not function as expected or successfully update to a newer DNS resolver service version. You can also no longer deploy new DNS resolver services from the site that is running the unsupported DNS resolver service
version. BlueCat recommends running the latest DNS resolver service version to
ensure that all features function as expected on the DNS resolver service.
