We are currently experiencing an issue with our Virtual Appliance 1.4.8 release. We have taken steps to mitigate the issue on all current 1.4.8 systems, and a rollback version is available. You will be updated in your normal maintenance window or you can follow the steps here: https://support.opendns.com/entries/69146214
If you do not see an upgrade option it's possible your download has not occurred yet. Please contact us at firstname.lastname@example.org and an agent can initiate the download. After the update, you will be on version 1.4.7. If you do not manually upgrade, you will be downgraded to 1.4.7 in your next maintenance window. Please feel free to open a ticket if you have any issues.
