Wireless Network Maintenance, 9/18/18 10PM
We will be performing an upgrade of our wireless controllers tonight at 10PM. Wireless networks will be unavailable for 15-30 minutes during the upgrade.
The software update intends to resolve some existing bugs which have been triggering unexpected controller reboots, occasionally causing network outages.
This maintenance will not affect BWRC, as that controller has already been updated. All other EECS Wi-Fi locations will be affected. (Soda, Cory, SDH, Jacobs, Blum, Calvin, HMMB BiD Center)

Brief Wi-Fi Outage, 9/14/18
There was a brief wireless network outage this morning due to a simultaneous crash of the primary and backup wireless controllers. The controllers self-recovered and we are now investigating the cause of the crash.
Wireless networks at BWRC were not affected.
Wireless networks at BWRC were not affected.

BWRC Uplink Issues, 8/23/18
Following this morning’s IST network maintenance we are experiencing issues passing traffic in and out of BWRC. We may have identified the root cause and are working with the campus NOC to resolve.
The impact specifically seems to be traffic between BWRC and EECS. Local traffic within BWRC is not affected. General traffic to/from the Internet does not appear affected. We are unsure about traffic between BWRC and the rest of campus outside EECS.
We will be performing an experimental configuration change tomorrow morning on the related EECS routers to try and alleviate the issue until the true cause can be addressed with IST. An update will be posted here before or around noon.

The upgrade is estimated to take around 45 minutes.

HMMB BiD Center Wired Network Outage 7/13/18 – Ongoing
The EECS wired network in the HMMB BiD center (169.229.63.0/25) is currently down due to a link issue. According to our router, the link has been down since Friday 7/13 at 22:47.
This part of the network is a little unusual, in that it is served by an EECS router but an IST switch and IST cabling for the last-mile. We have confirmed there seems to be no issue on our end and are working with IST networks toward a resolution.
Wireless networks in HMMB are not affected, including EECS-Secure and EECS-PSK.
Update 12:03 PM: We are in contact with IST Network Operations and they are aware of the severity of the issue. Due to heavy workload, they may not be able to address the issue until tomorrow, but they will look at it as soon as possible.

IT and Electrical Maintenance Shutdown, Sat. 6/16/18
On Saturday, June 16th, the campus high voltage team will be cutting power to **Soda, Jacobs, Etcheverry, and North Gate Halls** to complete critical power grid maintenance. The electrical shutdown is currently scheduled for **8AM to 1PM** and these buildings will be **closed** during this time to all but critical staff related to the maintenance projects.
We are also taking this time to perform safety tests in our server and network rooms, as well as replacing the failed battery backup system in our primary server room. As a result, **the outage window for most IT services** (other than basic network connectivity) **is 11PM 6/15 – 9PM 6/16**.
Anybody with computers and electronics in Soda and Jacobs is **STRONGLY RECOMMENDED** to power off their noncritical systems when leaving the office on Friday, June 15. Critical systems **MUST** be powered off by 6AM on Saturday the 16th. This includes machines hosted in the 340 Soda server room, and a separate message will be sent to those system administrators next week.
As most of EECS’ IT infrastructure is hosted in Soda Hall, this will have some impacts which are detailed below. This will affect all EECS locations which are not undergoing electrical maintenance: **Cory, Sutardja Dai and Blum Halls, the Calvin Lab, and BWRC** as well as remote users.
* **Network infrastructure** (wired and wireless connections, including DHCP and DNS services) **will be offline for a brief period between 6:00 and 6:30 AM** in order to perform annual Emergency Power Off and Fire Alarm tests in our network core. Basic networking (including DHCP/DNS) will be restored by 6:30 and should remain up for the remainder of the day for all locations outside of Soda and Jacobs Hall.
* The IRIS website and portions of the department website including personal homepages, as well as other IRIS services that depend on file storage, will be shut down **starting at 11PM Fri. 6/15**
* Storage services, including home and project file storage, will be shut down at **12 AM Sat. 6/16**
* All services are scheduled to be **restored by 9PM**, but may be online earlier if maintenance is completed ahead of schedule.
As the IRIS website will be unavailable during this maintenance, https://status.eecs.berkeley.edu will be available for in-the-moment status updates.

Campus Authentication Issues, 4/30/18
The campus CalNet Authentication Service (CAS) appears to only be functioning intermittently at this time. Services which rely on CAS authentication (AirBears2, campus VPN, many department and campus Web pages, etc.) may intermittently fail.
IST is working to diagnose the issue and will post updates at ucbsystems.org.
IRIS services which rely on IRIS authentication (i.e. EECS-Secure, many IRIS Web pages) continue to function normally. We are monitoring the situation and will post an update here when we have one.
Note that as the issue is intermittent and only pertains to authentication, you may be able to re-try a few times to authenticate successfully, after which the service you are accessing should behave normally. For example, it may take a few attempts to connect to AirBears2, but once you are connected the network should work.
