tl;dr: We're about to disable self-service creation of Debian Jessie
VMs. To request an exception, open a Phabricator ticket specifying your
need and reasons.

We're close to polishing off the last few Ubuntu Trusty VMs in the
cloud, which means it's time to start thinking about the upcoming
deprecation of Debian Jessie.
WMCS (and the WMF in general) will continue to support use of Jessie
well into 2020, so no immediate action is needed on the part of current
Jessie users. On the other hand, any /new/ work should definitely
happen on Stretch in order to postpone the inevitable OS-motivated
rebuilds as long as possible. In order to encourage that, we're going
to disable creation of new Jessie VMs in the next few days
If you believe that you are a special case and need a Jessie VM anyway,
please open a phabricator ticket explaining your reasons and specifying
name and flavor for the VM to be created, and WMCS staff will make it
for you.
