Changes to the hosts that upgrade your VAs.
We are in the process of transitioning our VA upgrade infrastructure to improved hosting.
To continue receiving VA upgrades, please make sure your firewall allows TCP traffic on port 443 outbound to disthost.umbrella.com/18.104.22.168 in addition to disthost.opendns.com.
If you do not set explicit outbound rules on 443 from your VA or from your network, or you had not previously added an exemption for 'disthost.opendns.com', no action is required.
For any questions, please contact support at firstname.lastname@example.org.
