Computing at CLASSE homepage

On Tuesday, July 29, the CLASSE Computing homepage will be updated - the new homepage will be the Quickstart Guide to the basics of computing as done at CLASSE. It's currently available at https://wiki.classe.cornell.edu/Computing/CLASSEQuickstartGuide2014 Comments and corrections will be gratefully accepted at service-classe@cornell.edu

CLASSECluster upgrade to Scientific Linux 6.5

At approximately 10am Tuesday, July 22, the CLASSE Linux Cluster will start upgrading to Scientific Linux 6.5. During this upgrade, there may be periodic delays accessing web, database, or file system services served from the CLASSE Cluster. We expect this work to be complete by 2pm.

Retirement of legacy file systems

After repeated disk failures on a decades old file server, the CLASSE IT group will be archiving the following file systems to tape and removing them from service. Any data from these file systems can be restored as needed with a ServiceRequest.

Archive IMAP Server (lnx120) outage

To prepare for the upcoming Air Condidtioner replacement in the Wilson computer room, CLASSE's Archive IMAP Server (lnx120) will be moved from Wilson to the PSB on Monday, 7/28, at approximately 7am. During transport, mail stored on lnx120 will not be available.

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.
