The machine room that lists.openbsd.org is in will be undergoing
maintenance Saturday April 14th. As a result, the list server will
be taken down at 6:00am MDT. It will be back up by 5pm MDT at the
latest.
This also affects ftp.usa.openbsd.org (aka anoncvs3.usa.openbsd.org)
which is located in the same machine room.
