You, seemingly, do not have much knowledge on UUNET.

Why, do you think, UUNET as a company named so?

It was an organization to offer connectivity to UseNET but some
used the word to just mean UseNET. See, for example:

	https://docs.oracle.com/cd/E19957-01/805-4368/gavzo/index.html
	UUNET
	(n.) A network that carries electronic newsgroups, aggregates
	of many electronic messages that are sorted by topic, to
	thousands of users on hundreds of workstations worldwide.

Declared in map files used by pathalias? But that's not my point.

UUCP links were not permanent but scheduled. See, for example:

	https://www.ibm.com/docs/en/zos/2.4.0?topic=systems-schedule-periodic-uucp-transfers-cron
	Schedule periodic UUCP transfers with cron

Such initial attempts were not so elegant or scalable.

UUCP networks as DTN were brought to perfection through
integration with the Internet relying on DNS MX RRs.
