Edit: Update Rollup 18 is now available for Exchange 2010 SP3 see the post Exchange 2010 SP3 Update Rollup 18 installation tips.
On 17th March Microsoft released the Exchange 2010 SP3 Update Rollup 9. I’ve waited a bit longer than usual to test and depoly the update due to the issues with Update Rollup 8 being released and then pulled, then re-released a few days later.
I’ve installed this on my test SBS 2011 server, it took just 9 minutes 30 seconds from start to finish, and my test SBS server isn’t very powerful. So I wouldn’t expect this to take much longer than this in production.
The new update has been available for a month now, and I have not seen any issues reported with it so I suspect it is safe to deploy in your production environment.
The Update Rollup 9 for Exchange Server 2010 SP3 contains the fixes for the security issue that is described in KB3030085 and the following Microsoft Knowledge Base (KB) articles:

While looking for others experience of installing the update rollup I’ve come across a few suggestions that might help speed the install up and a few best practice tips.
1. Reboot the server prior to installing the update rollup. If it has been up for a while a reboot will make sure it is in a know good state.
2. Run the update from an elevated command prompt.
3. In Internet Explorer, deselect “Check for Publisher’s certificate” and “Check for server certificate revocation”, from Internet Options, Advanced tab, Security options.
4. Disable antivirus software.
5. Have a full backup and a system state backup of the server.
6. Make sure the SBS console is closed if installing the update on SBS 2011.
7. Backup any OWA customisations you have in place.
8. Stop any Backup Exec services if you have it running locally.
While the update is installed it will automatically stop Exchange and IIS services, and restart them again once complete.
Once the update has finished, remember to undo the changes made in steps 3 and 4 above.
