How exactly can you tell it? Do you have any packet capture?
Yes, I ran a tcpdump this morning to confirm what Hetzner told me. a tcpdump on "br0", looking for the two local link addresses from my two DomUs.
see attached. The DomU with 'fe80::216:3eff:febb:ac82' is currently down. It was running 15.3, but failed to boot after the latest 'zypper dup'. -- Per Jessen, Zürich (19.8°C)
