My totally unproven/unfounded theory - HG created the new domain himself.
The 3/30/23 email would argue against this theory. It contains the sentence "Please revert upon email receipt." Americans would say "Please reply" and this use of "revert" suggests the writer is an English speaker from India.

1. return to (a previous state, practice, topic, etc.).
