Listserv mailing lists will be unavailable on the morning of Thursday, September 24th, 2015, between 0500 and 0600, while the server is moved to a new cluster. During this time, mail will be queued for later delivery, but the Listserv management web interface will be unavailable.

There should be no end-user impact and no changes for Listserv mailing list owners or subscribers will be required once server maintenance has completed.

Should there be any change to expected time of completion or other service impact this notice will be updated.
