I'm suggesting a lot more notification than 6 months before is
switched off.  And corroborative announcements backed up from authoritative
sources, not just a single email to nanog.  It turns out that the Internet
extends far beyond the borders of continental north america, and this
change affects everyone who runs a resolver server.

It would be really good to have a formal public statement of intent from
UMD about their long term plans for after retirement so that we
don't have a repeat of the L root hijacking debacle in 2008.

Everyone is extremely appreciative of the work that UMD has done in hosting
this service since 1987.  However, hosting a root server is a pretty big
responsibility which includes maintenance of not just the existing
addresses, but also all historical addresses to ensure that people who hit
them after retirement (whether now or 20 years down the line) are not
served bogus data.
