General Filesystem Outage: Tuesday, 30-Nov-2021 @ 5:00 PM

On Tuesday, 30-Nov-2021, there will be a general CLASSE filesystem outage from 5:00 PM to 6:00 PM. Many project and group filesystems will be affected, including the main CLASSE user and temporary disks (\\samba\user and \\samba\TEM). The CHESS and CESR data acquisition and control system filesystems will not be impacted. This outage is required to update the firmware in our central storage systems to improve stability and performance. To receive real-time updates on this work, you may subscribe to the CLASSE-IT-NEWS-L mailing list, and please submit a ServiceRequest with any questions or concerns.

Service Glitches Possible: Tuesday, 07-Dec-2021 @ 9:00 AM

On Tuesday, 07-Dec-2021, from 9:00 AM to 12:00 noon, there is a possibility of brief service glitches as we conduct routine UPS load testing. Please submit a ServiceRequest with any questions or concerns about this maintenance work.

OpenVPN Retirement: Monday, 28-Feb-2022

On Monday, 28-Feb-2022, we plan to shut down the legacy CLASSE VPN service, OpenVPN. At this point, CLASSE personnel should begin to use our new VPN, known as Pritunl. Instructions for using Pritunl from CLASSE-managed and personal computers are available at ClasseVPN. For enhanced security, our Pritunl deployment includes two-factor authentication via CLASSE Duo (see below).

CLASSE Duo: Two-Factor Authentication

In light of the increased threat posed by ransomware and account compromises, CLASSE is adopting the use of Duo two-factor authentication for enhanced security of web services and remote logins. CLASSE Duo operates very similarly to Cornell's Duo service, although a separate CLASSE registration is required. To enroll in CLASSE Duo, please see these instructions for our web-based management portal. CLASSE Duo is currently required for the new VPN (Pritunl), and we plan to enable it for additional services in the future. If you have any questions or concerns about CLASSE Duo, please submit a ServiceRequest.

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.
