Ah, okay. I didn't realize that had taken place. Thanks for the additional context.

Theoretically, yes, they are ready to use and should just work. We can only run one job at a time currently though because we don't have enough quota in the region where the cluster is deployed, but that should be enough for testing. @lnihlen is working on getting additional quota. I think it would probably make more sense to use the Google hosted runners given it doesn't require any budget from the foundation, and lets us consolidate on a single system.

I think our runners will also be more powerful too (configured to be 56 vCPUs), but depends upon how the depot runners are configured.
