We had to scale the frontend to multiple pods (2 at the moment).

We need to track this change in Git.

HPA will handle this dynamically for us: #1059

Housekeeping: reviewing open issues. @ktdreyer is this still relevant / something you plan to work on? If not, we'll close it out. No pressure either way — just trimming the backlog.
