keys.gnupg.net is a DNS round robin pointing to several hosts run by
different parties. This works just fine if you depend on the PGP Web of
Trust for your authenticity and privacy, because mutually untrusting
hosts in different administrative domains can provide assertions and
ones that misbehave can be ignored or whatever.
This model works much less well when crossed with the TLS X.509
certification scheme, where a Trusted Third Party is expected to attest
that a specific Private Key entitles the posessor to complete control of
traffic associated with the given name.
As a result, https:// and hkps:// protocols are are more or less
fundamentally incompatible with volunteer-operated multi-organizational
load sharing schemes based on DNS round robin records.

The catch is that most Internet users now assume that HTTP is the only
(or at least the preeminent) way to use the internet. DNS round robin
application schemes harken back to an earlier, multiprotocol Internet.
