Upgrade of LNX201 to SL7, Tue 10-Jul-2018 @ 10:00 AM

Continuing with our migration from Scientific Linux 6 to 7, LNX201 will be upgraded to SL7 at 10:00 AM on Tuesday, 10-Jul-2018. LNX201 will be unavailable at this time and should return to service by 1:00 PM. As a reminder, we are migrating all CLASSE SL6 workstations to SL7. If you have not yet done so, please submit a ServiceRequest to schedule an SL7 upgrade of your SL6 workstation.

New Firefox ESR for CLASSE Managed Computers, Tue 10-Jul-2018

CLASSE uses the Extended Support Release (ESR) version of Firefox for long term stability while also keeping up to date with security updates. Next week, on Tuesday, 10-Jul-2018, Firefox on CLASSE Windows computers will undergo a major upgrade, from version 52ESR to 60ESR. We will also be migrating to Mozilla's recommended 64-bit builds at the same time. [Firefox on Scientific Linux computers will be upgraded at a later date.] Changes in Firefox 60ESR include:

• Extensions are a different platform. If you've installed any, they may break, or may not be supported anymore.
• No plugin support other than Adobe Flash Player. (If you are using Java on Linux as a plugin, it will stop working.)
• 64-bit Firefox on Windows uses more RAM than the 32-bit version. It is not unusual for Firefox to use 4 GB of RAM when you have multiple windows or more than 10 tabs open. Resource intensive sites (like YouTube) may also use a lot of memory. If you find degraded Firefox performance after the upgrade, please submit a ServiceRequest to discuss options.

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.
