Thanks @Krenair. What will it mean for Ubuntu support to be removed?

Migrating before then will probably not be a huge problem, but I'd like to understand the worst case scenario if there are unanticipated problems.

At some point "soon" (probably not actually until April 2019) code explicitly supporting Ubuntu will be removed from ops/puppet.git. Once this happens it is likely that Puppet runs on any remaining Ubuntu instances will start failing. That will put the instances at risk of not being accessible via ssh, NFS mounts failing, and not being reconfigured for other core infrastructure changes that may happen in the larger Cloud VPS environment. The worst case scenario is fundamentally the instance becoming an unrecoverable brick.

We are skipping this project in today's operation due to short notice period.

Wes and I spent today getting a new debian server spun up, configured, and set for deployment. We got the app up and running, so what remains to be done is:

• Put up a notice about pending downtime
• Disable the old server
• Create a mysql dump
• Load the dump on new server
• Redirect outreachdashboard.wmflabs.org to the new server
• Verify that things are working smoothly
• Destroy the old server

Our all-staff meeting is next week and we want to have plenty of wiggle room in case things go wrong, so we are planning to complete these final steps the week of February 12.
