A power outage to Soda Hall which began around 12:30pm on June 21, 2017 has taken out many IRIS services. This backup website will be updated until our main website is working again.
Power has been restored to Soda Hall and staff are bringing up network equipment now. The power conditioner in the main Soda machine room is having problems recovering. Electricians are on site assisting.
This incident was fully resolved around 12:30am on June 22. See this IRIS news article for details.
The EECS networks became unreachable around 1:20pm on Monday, April 10. Staff are investigating.
Update (2:15pm): Staff investigation found the problem to be at or with one of the department border firewall devices. The secondary firewall device has been made primary now, and traffic is routing properly. Staff will further examine the problem firewall device, to narrow down the specific cause.
We ran into a number of difficulties on the electrical side which delayed restoration of services, but basic networking (wired and wireless) were brought back at approximately 12PM.
At this time we are experiencing some slowness in the LDAP system, and we have also encountered trouble in bringing the NetApp file servers online. As a result the department website and file storage, as well as other services which rely on them, are still offline.

We will have a full system shutdown on Thursday, December 22nd at 7:30 AM to perform necessary fire and emergency power testing in our server rooms. The entire EECS network and all hosted resources will be offline during this maintenance.
This will affect networking in the following locations:
Wired and wireless networks offline:
- Soda Hall
- Cory Hall
- Sutardja Dai Hall
- Jacobs Hall
Wireless networks offline, wired remains online:
Hosted resources such as the EECS website, file servers, etc. will be offline and globally inaccessible.
The facilities maintenance window is scheduled from 7:30 AM to 1 PM, but we anticipate the network and critical services should be back by 11AM if all goes well.
The intent is to perform these tests annually going forward; however we will learn from this year’s procedure and aim to keep more critical services online in the future.
If you have any questions about this maintenance, please contact email@example.com.
On the morning of Thursday, November 24 (Thanksgiving Day), we will be performing some disruptive maintenance on the department fileserver:
- Recable to new network datacenter switches.
- Upgrade cluster switches firmware.
- Upgrade NetApp OS.
Department fileservice will be unavailable during the maintenance window, approximately 10am until 1pm. Many services that rely on access to department fileservice (home directories, webservice, repo service, etc), will either be offline or will fail to work during this window. All NFS and CIFS mounts will be affected.
We expect most, if not all, clients to recover automatically once the fileservers are back online. This news item will be updated to indicate when the maintenance is completed.
Systems still experiencing mount issues after the maintenance window, would need to remount or reboot.
FILESERVER MAINTENANCE COMPLETED

Scheduled Maintenance Resolved
Systems on new datacenter network switches. All firmware updates completed. Netapp OS upgraded on all nodes. If there are any NFS or CIFS issues please reconnect and followup with helpdesk if there are outstanding issues.

Services Affected IRIS Website
Begins 9:00 a.m. Nov 13, 2016
The IRIS Network and Roster applications will be unavailable Sunday November 3 between 9am and 10:30am for system maintenance. The Oracle database behind these applications is having quarterly patches applied.
Staff are investigating a network outage affecting all EECS network hosts. The outage began at about 6:25am September 22.
At this time, it’s unclear whether the outage is due to EECS network equipment, or upstream with campus networking.
UPDATE: Cause was due to a loss of default routes normally advertised by campus BGP. The issue was isolated and the campus NOC restored the routes shortly before 10AM.
