I wonder if .exe in the domain sets of all kind of overenthusiastic "safety" mechanisms in search engines, AV software, etc.

Interestingly, it's the .xyz on our VM domain that causes problems. It's apparently far more of a problematic gTLD than I realized. E.g. it appears Southwest Airlines blocks the entire thing, as do some enterprise networks are working with.

(We have a fix for this coming in a few weeks.)
