The LISTSERV mailing list service upgrade has been postponed and will not take place September 16.
A side-effect of the new LISTSERV support for Unicode characters is that the search indexes for /all/ mailing list archives must be rebuilt the first time the software is started after the upgrade, and before the service becomes available again. Based on my calculations, this could actually take 20 hours with our rather large list archives, so we're going to have to rethink how this upgrade will take place. Particularly annoying since the software upgrade itself will likely take about 30 seconds...
