As announced previously on this list [0] we are in the process of replacing the old Ubuntu Trusty instances in Toolforge with fancy new Debian Stretch instances.
== Remaining timeline == * Week of 2019-03-04: Switch login.tools.wmflabs.org to point to Stretch bastion * Week of 2019-03-25: Shutdown Trusty grid
The DNS entry for "login.tools.wmflabs.org" will be updated to point to a Debian Stretch bastion rather than the old Ubuntu Trusty bastion soon (like right after I send this email). This change will cause many ssh clients to alert about a change in the ssh host fingerprint. Updated fingerprints will be posted on wikitech [1][2] once the switch has been made.
The legacy Ubuntu Trusty bastion will still be reachable as "login-trusty.tools.wmflabs.org" until that instance is deleted during the week of 2019-03-25.
In just over 2 weeks we will be shutting down the Trusty grid for good. Any tools that have not migrated to either the Stretch grid or the Kubernetes cluster at that point will be forcibly shutdown. Nothing will be deleted in the tools' $HOME directories, but any Trusty grid jobs will be stopped. Any crontab file remaining on the old grid's cron server will be archived as "$HOME/crontab.trusty.save". Maintainers who somehow missed all of the announcements will be able to login and restart their tools on the Stretch grid or Kubernetes.
See https://wikitech.wikimedia.org/wiki/News/Toolforge_Trusty_deprecation for additional information and tips on common problems that have been found thus far.
