Thank you for bearing with us as we made the move.
The last server rebuild we did was on May 17th 2015. We spun up this master server in 2014! We then did a rebuild using Ubuntu 14.04, that then got upgraded to 16.04 and has been running like a top ever since.
I was running on Ubuntu 16.04, it is not officially at end of life until April 2021. Rock solid performance and security.
I was going to use another set of Ubuntu based servers, but I chose another flavour of Linux. There was several factors that led the admin (Me / ~Q~) to switch over to CentOS.
With Centos we have until June 30, 2024 before an OS upgrade for the network.
Just for kicks I did the OS upgrade for Ubuntu on the old Master Server…..
UPDATE: The upgrade to 18.04 completed with out an issue. Sharing this here for the archives a pick of the upgrade. This server is about to be decommissioned.
