Part of the Soda 4th floor wired network (primarily RISE Lab) was offline today between 15:34 and 15:46 due to a misbehaving private network. The private network has been temporarily disabled and service has been restored.
Cory Hall Network Outage 7/27
The Cory Hall network was offline from 15:16 – 15:34 this afternoon due to a malfunction in the building core switch. The issue has been resolved.
Rolling Wi-Fi Outages, 5/18 – 5/28
Beginning Tuesday, May 18th, we will be performing wi-fi upgrades in all EECS network service areas (except BWRC and HMMB). Work will generally proceed floor-by-floor, with each building experiencing rolling wi-fi outages over a two to three day period. All wireless networks will be offline: EECS-Secure, EECS-PSK, AirBears2, eduroam, and CalVisitor.
Please see the schedule below for information specific to your building. If you are currently working on campus, and depend on the wireless network in these locations, please consider working from an alternate location during your building’s maintenance dates. We also recommend checking this post regularly in case of schedule changes.

This Friday, May 7th between 8 and 9AM, we will be performing scheduled maintenance of the EECS-PSK wireless network to prepare for our upcoming wi-fi refresh.
Update: This maintenance was completed without incident and the EECS-PSK network is back online. If you notice any issues, please email us at help@eecs.berkeley.edu.

All Cory Hall networks are offline since 23:24 last night, due to an apparent electrical issue in the Cory network core.
As we have not received an immediate response from facilities services, network staff are preparing to go onsite to investigate.
Wi-Fi Outage, Cory and Sutardja Dai Halls
From around 6:15 this morning, all wi-fi networks are offline in the following locations:
- Cory Hall 1F
- Cory Hall 3F
- Cory Hall 5F
- Sutardja Dai Hall 2-7F
- SDH NanoLab 5/6F
We have determined the root cause (a firmware bug) but are unable to resolve the issue remotely. We expect service to be restored later this morning.
Update: Service has been restored in all areas as of 10:45AM. Please email help@eecs.berkeley.edu if you notice any continuing issues.
SDH 1F Wi-Fi Outage
As of around 6:46 PM, Sutardja Dai first floor wi-fi is offline due to an apparent failed switch. Staff will be onsite tomorrow and we expect to restore service by the early afternoon.
Update 10/15 8:13AM: Thanks to an assist from one of our IST colleagues who was in the area, wi-fi service on SDH 1F has been restored earlier than expected. We will continue to monitor for stability.
Soda Hall Power Shutdown Tuesday 8/18 8am-8pm
On Tuesday, August 18th, Soda Hall building power will be shutdown from approximately 8am to 8pm for required facilities work. There will also be sporadic brief outages to various IRIS services between 9am and 2pm due to network maintenance.
Our primary datacenter and network core will receive backup generator support and we generally expect all services to remain online throughout the day. However, we are taking the opportunity to perform a number of network maintenance items which would have otherwise necessitated multiple outages later in the year.
As a result there will be multiple brief interruptions to various services including NetApp file servers, DHCP and DNS service, and the login.eecs and winterm terminal servers. We expect each individual interruption will last for less than five minutes, and this work will be performed between 9AM – 2PM. This post will be updated when all network maintenance is complete.
After network services are fully restored, sysadmins may need to reboot their systems, restart/remount nfs file systems, etc. to get fully back online.

The Jacobs Hall network was unstable from approximately 11AM to 11:45AM due to a router malfunction. We restored service and will continue to monitor the router. Please email help@eecs.berkeley.edu if you continue to notice a problem.
IPv6 Coming to EECS Wi-Fi This Weekend (Feb. 15-16)
This weekend, 2/15 through 2/17, we will be enabling IPv6 on the EECS wireless networks. The current plan is to enable on EECS-PSK Saturday, EECS-Secure Sunday, and monitor on Monday. The EECSv6 test network will be abated later in the week and any test users should return to using EECS-Secure.
If your device is registered on the EECS network and has its IPv6 stack enabled, you will receive IPv6 connectivity without any further action needed.
We recommend everyone confirm that their wireless devices have an IPv6 firewall enabled to maintain the security of your machine.
Please email help@eecs.berkeley.edu with any questions or concerns about our IPv6 rollout.
