From around 6:15 this morning, all wi-fi networks are offline in the following locations:
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.
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.
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.

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.
The certificate used by the EECS-Secure authentication servers (clearpass.eecs.berkeley.edu) has been updated. Wireless devices using EECS-Secure may prompt you to accept the updated certificate before you can reconnect to the network.
Updated certificate files and fingerprints have been published here in case you would like to verify the new certificates or install them on a device.
Today between 1206 and 1212, EECS networks were isolated from the outside world due to an unanticipated routing protocol behavior during a reconfiguration related to our firewall replacement project. This has been corrected and there will be no further issues.
We will be performing firmware upgrades on the EECS core routers at 3AM on the mornings of Saturday 8/31, Sunday 9/1, and Monday 9/2 (Labor Day weekend). Each outage is expected to last under 20 minutes; however a full hour has been scheduled in case of unanticipated issues. Specific times and expected impact for each maintenance window is below.
These upgrades were completed successfully as of Monday 9/2 at 4AM.
[Read more…] about Scheduled Network Maintenance: Labor Day Weekend 8/31 – 9/2, 3-4AMOn the morning of 4/21 (Sunday) at 1AM we will be performing a firmware upgrade of the wireless controllers and APs. Wi-fi will be out of service for 10~30 minutes during this time.
Edit: this post originally stated the upgrade would occur on 4/21 (Saturday) and has been updated to reflect the correct day of the week (Sunday).
