I will be taking down all of the CentOS 6 and SL 6 based servers to make an image and reboot to incorporate a kernel and about 500 other updates this evening.  This will affect everything for about 20 minutes when the physical hosts are rebooted and it will also effect scientific, shellx, mail, ftp, mx1, and mx2, which at present are all CentOS 6 based.
