GlassFish and Tomcat Service Restart: Tuesday, 27-Nov-2018 @ 12:00 Noon

On Tuesday, 27-Nov-2018, there will be a Java update on our Linux systems. For good housekeeping, at 12:00 noon, we will restart the GlassFish and Tomcat web application servers, which will momentarily disrupt the following services: cesrglass, cesrglass2, glassfish-dev, pwm, xmpp, and webprotege.

CLASSE VPN Certificate File Update

As we mentioned in last week's newsletter, because of an expired security certificate, all computers (both personal and CLASSE-managed) that connect to the CLASSE VPN need to be updated with a new certificate file.

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.
