Reverse proxy returns 502 for one container after every host reboot

Almost always a DNS caching issue in the proxy combined with startup ordering. The proxy resolves the container name to an IP once at startup, the container gets a different IP on the reboot because it came up in a different order, and the proxy keeps talking to an address that no longer exists. Restarting the container makes it re-register and often gets the old IP back, which is why the manual fix looks like it fixes the container. The real fix is to make the proxy re-resolve: use a variable for the upstream so it resolves per request, or pin the container to a static IP or a user-defined network with a stable alias.

Is it normal for a used enterprise drive to arrive with 41000 power on hours

Normal for the category and not a reason to panic on its own. Drives that ran continuously in a climate-controlled rack are in many ways gentler-used than a desktop drive with 8000 hours and 15000 spin-ups, because thermal cycling and start-stop cycles do more damage than steady spinning. Clean SMART at 41000 hours is a genuinely good sign. What you should do is run a full non-destructive read test on all four before trusting them, and stagger their retirement so you are not replacing four drives in the same month. Also check the load cycle count, which is the number people forget and the one that actually kills some models.

Wrap the single hive or build a quilt box for minus 20 winters

Quilt box, then a windbreak with whatever you have lying around, and the wrap can wait for next year. Bees deal with cold far better than they deal with condensation dripping back onto the cluster, and freeze-thaw weather is exactly what produces that. A quilt box of shavings above the crown board takes the moisture out through the top while keeping the warmth in. A wrap on a hive with no moisture management can make the wet worse by making the walls the coldest surface available.
