Looks like all the Arcade instances to me! 👍

Do we have a plan (or desire) to recreate these at all, or are they staying removed for the foreseeable future?

I have no plans and, unfortunately, am unsure about my personal desires here. I was hoping someone had the credentials so we could look into metrics. It's an interesting mechanism, but sustainable maintenance is top of mind for me. If this is something that interests you, bring it to a team meeting, and let's discuss 🙂

Thanks @akeller. I'm trying to check if we can find the credentials used there and we can take a decision on this later.

Since we don't have access to Arcade's credentials, we cannot further evaluate this as an offering we want to maintain/expand. However, we could consider doing something similar in the future with a well-scoped issue, epic, or experiment.
