CELS Maintenance Weekend, August 14-16

Hey everyone. In building the General Compute Environment (GCE), one of the tenets we held to is keeping it up to date and secure. Part of accomplishing this necessitates some outage windows to apply needed patches and updates in cases where we do not have a method for doing them live. We are planning to do these quarterly, and due to the fact we often need to rely on BIS-provided services we cannot have them happen on the same weekend as BIS maintenance weekends.
We are planning the first official GCE maintenance weekend on August 14-16.
Which systems will be affected:
* Friday, August 14: None * Saturday, August 15: * 11:00 AM through 4:00 PM: GCE mysql servers and their supported services including: JLSE Confluence, wordpress.cels.anl.gov, Userbase3 Development database, and other internal-facing services * Sunday, August 16 * 11:00 AM through 4:00 PM: GCE Fileservers and their supported computers (GCE workstations, compute nodes, home nodes)
During each of the windows above, you can expect the affected services listed to be unreachable for varying stretches. During the Saturday window, since this affects virtualhelpdesk.cels.anl.gov, you can follow @celssys (twitter.com/celssys) on twitter for updates.
Please let us know if there are any events or situations that would require us to move these windows.
Thanks!
