Temporarily disable UNS

UNS was compromised in the SquareSpace domain hack triggered by the
Google Domains shutdown. They've turned off services but DNS hijacking
means we will avoid trusting until things are back to normal, at which
point an updated API key will be issued and UNS will be re-enabled with
the updated key.
