Hello,

The Scientific Linux distribution servers will be unavailable for about 
2 hours at November 29 2017 14:00 CST (Chicago).

Downloads, yum operations, and mirror syncs will fail against the 
following hosts:

* rsync.scientificlinux.org
* ftp.scientificlinux.org
* ftp1.scientificlinux.org
* ftp2.scientificlinux.org


For your local time you can run date -d '2017-11-29 14:00 CST'

Thank you for your patience while we perform this maintenance.

Pat Riehecky
