In an attempt to identify abandoned VPS projects, I've created a wiki page that lists all existing projects, here:
https://wikitech.wikimedia.org/wiki/Cloud_VPS_2018_Purge
Currently 85 projects[2] on that list are unclaimed. If you are a VPS user, please visit that page and mark any projects that you use as {{Used}}. Note that it's not necessary for you to be a project admin to mark something -- if you know that you're currently using a resource and want to keep using it, go ahead and mark it accordingly. If you /are/ a project admin, please take a moment to mark which VMs are or aren't used in your projects.
When October arrives, I will shut down and begin the process of reclaiming unused projects.
If you think you use a VPS project but aren't sure which, I encourage you to poke around on https://tools.wmflabs.org/openstack-browser/ to see what looks familiar. You can also log in to http://horizon.wikimedia.org which will provide you with a handy menu of projects that you are currently a member of.
Thank you!
-Andrew and the WMCS team
