We will update this post when the work is complete, or if there is an unforeseen impact to the production networks.

Web services upgrade, Friday July 5

July 3, 2024 by Rob McNicholas

IRIS-provided web services will be migrated to new Red Hat 9 servers on Friday, July 5th beginning at 10am. This will affect people.eecs, www2.eecs, and all the project websites hosted by IRIS. This should be transparent to most people, but users of apps.eecs.berkeley.edu might have to upgrade their code due to new versions of the supported languages. These people have been previously contacted.

As usual, please send any questions or concerns to help@eecs.berkeley.edu.

component	Current Version	Upgraded Version after July 5
apache	2.4.6	2.4.57
python	2.7.5	3.9.18
php	5.4.16	8.2.13
perl	5.16.3	5.32.1

Upgrading dhcp.eecs Friday, July 5

June 26, 2024 by Lars Rohrbach

On Friday, July 5, from about noon to 2pm, we will be performing an OS upgrade for dhcp.eecs.

During this time, DHCP service will be handled by our backup DHCP server, so there should be no significant interruption of service — but no new DHCP updates will be processed (i.e. new system network registrations will not become effective until after the upgrade is complete).

Soda Hall 2nd Floor Power Outage on June 13, 2024

June 3, 2024 by Lars Rohrbach

As noted following the January 4th Soda Hall power outage, an additional power outage for the second floor of Soda Hall is being scheduled to complete a circuit breaker replacement. Electrical power to the Soda Hall second floor will be down during much of the day on Thursday, June 13, 2024. Critical systems will be down from about 6am until perhaps 5pm.

Of primary note is that the department NetApp fileservers will be down, so any systems that depend on HOME or PROJECT storage will be shutdown or nonfunctional. Services that will be unavailable during the maintenance period include: department webservice (including people.eecs, www2.eecs and all other IRIS-hosted web sites), IRIS account & network forms, login servers (login.eecs, login-mfa.eecs, winterm.eecs), print server print.eecs, and outgoing SMTP server gateway.eecs.

Any systems that remain powered-on but make use of HOME or PROJECT storage may become unresponsive during this time. Rebooting after maintenance is completed is usually recommended.

Services that will remain online and available include: DHCP, EECS Active Directory, EECS LDAP, wired networking, DNS (cronus.eecs), and maillists (lists.eecs), and the main department website eecs.berkeley.edu.
