Site status page

I think a page with the overall health/metrics on the site could be helpful. In particular, I’m thinking about the size of the Strava activity backlog.

Background: I’m another new user that is watching old activities arrive from Strava in batches. New activities arrive, but old ones have been paused for a few days. I see the thread where this has happened many times in the past, so I’ll just wait some more.
