We're drawing close to a painful migration event[1], during which we will (probably) have to copy VMs between hosts one project at a time, largely by hand. For that reason, I'm feeling even stingier than usual about preserving unused and/or abandoned projects and instances.
It's been a couple of years since we last did this, and I'm sure there are some newly forgotten projects in the cloud. So, I've created a wiki page the lists all existing projects, here:
https://wikitech.wikimedia.org/wiki/Cloud_VPS_2018_Purge
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. Worst case, just email cloud@lists.wikimedia.org with a description of your use case and we'll sort it out there.
Exclusive toolforge users are free to ignore this task.
Thank you!

[1] The eqiad->eqiad1 migration, also known as the 'nova-network to neutron' migration which I hope to write more about soon. It won't happen by surprise, I promise.
