This solution applies to all Barracuda Networks products with web interface-downloadable firmware updates.
Barracuda Networks occasionally performs a slow roll out of firmware versions. These roll outs use a random serial number election process, so some administrators will see the new version as available and some will not. If another firmware version is released and the serial number election is randomized again, your Barracuda Networks product may not show the latest version as an available download. If you have any questions, please feel to contact Barracuda Networks Technical Support.
