I've noticed that on high traffic volume to storage nodes or a new node being added, the admin API (with of course, the metrics endpoint and presumely health) becomes unresponsive, Prometheus cannot reach it which then triggers alerts.

This likely depends on the timeout that you allow for scraping, and the level of activity on the metadata... we could maybe improve things here but I would not say it's unexpected
