I started seeing this too around April 18th @ 11:08 on all my 10.04 Ubuntu servers.
I eventually found a static copy of my motd, which was never getting updated in /etc/motd.tail.
I have no idea what put that there, but given it happened on all my servers it must have been a package update and yet looking at the dates in /var/lib/dpkg/info none of the packages which touch /etc/update-motd.d/* have changed recently. Some of the servers only I have access to, so this is very odd...
