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.
