Just after midnight 12/20/2014 (tonight) [correction, since it will be after midnight, it will actually be 12/21/2014] I will be taking the web, ftp, and scientific.eskimo.com shell servers down for imaging so that we have current backups complete with all the recent security upgrades to restore from should it become necessary.
The expected downtime is about 25 minutes for web and ftp and about 45 minutes for scientific.eskimo.com.
Experience has taught me that nothing invites disaster like not being prepared for it.
