Instructional & Research Information Systems
We are currently investigating a partial wired network outage on the third floor of Cory Hall. Wireless networks should not be affected. Updates will be posted here when available.
Update: We identified an issue with one of the third floor switches and network connectivity has been restored. Please email us at help@eecs.berkeley.edu if you notice any continuing network issues.
On Friday, May 19th at 6:30AM, we will cease public broadcast of the EECS-PSK wireless network. The network will continue to exist and devices already configured to use it will be able to continue to do so throughout the Summer semester. However, it will not be available as a visible option to new devices which are not currently configured to connect to EECS-PSK. In other words, EECS-PSK will become a hidden SSID.
We recommend users of EECS-PSK immediately begin transitioning to either eduroam or Berkeley-IoT. eduroam is appropriate for devices such as laptops, desktops, phones and tablets; whereas Berkeley-IoT is appropriate for simpler devices which are not capable of authenticating to eduroam (i.e. devices which cannot perform 802.1X authentication).
Information about how to connect to eduroam and Berkeley-IoT is available at https://technology.berkeley.edu/wi-fi.
Please read the full post below for more information, including the final shutdown date for EECS-PSK. Contact us at help@eecs.berkeley.edu if you have any questions or concerns.
[Read more…] about Announcing Retirement of the EECS-PSK Wireless NetworkBetween 12 and 4PM on Thursday, December 29th, we will be replacing the access switches which serve the second floor of Cory Hall. During this time, there will be significant disruptions to the wired and wireless networks on the second floor, the second floor mezzanine, and possibly also the Cory Hall roof.
Update 12/29 16:30: This maintenance is complete. Please email help@eecs.berkeley.edu if you notice any network issues.
Between 11AM and 4PM on Wednesday, December 28th, we will be performing maintenance on the Soda Hall core router. Most Soda Hall wired networks will not be affected by this maintenance due to redundant links. However, Soda Hall and BWRC wi-fi, as well as BWRC’s uplink to the outside world, will experience a number of interruptions during this time.
Update 12/28 15:15: This work has been completed and all networks are online. Please email help@eecs.berkeley.edu if you notice any issues.
Between 12 and 1PM on Tuesday, December 27th, we will be performing maintenance on the Soda Hall root switch. All Soda Hall wired and wireless networks will experience interruptions during this time, except for most of 290 Soda, which will remain online. (Some Instructional systems in 290 will be affected)
Update 12/27 2PM: This maintenance was completed and all networks should be back online. Please contact us at help@eecs.berkeley.edu if you have questions or notice any issues.
Between 1 and 2PM on Tuesday, December 27th, we will be performing a firmware upgrade on one of our two redundant border routers which connect the EECS networks to Campus and the Internet. No interruption is expected, as the other border router which is not being upgraded will be able to handle all network traffic during this maintenance.
Update 2:15P: This upgrade has been completed and both border routers are back online. Please email us at help@eecs.berkeley.edu if you notice any network issues.
This week, we will be performing network maintenance to complete the decommissioning of our old border firewalls. The work will be performed in two stages; the first between 11AM-12PM on Tuesday the 13th, and the second between 11AM-12PM on Wednesday the 14th.
We do not expect this work to have any impact to network connectivity, as the vast majority of traffic flows were migrated to our new firewall earlier in the year.
Please email help@eecs.berkeley.edu if you have any questions, or if you notice any unusual network behavior.
Update 12/14: This work has been completed without any network impact. Please email us at help@eecs.berkeley.edu if you notice any issues.
At 7AM on Wed. January 4th, the EECS-Secure wireless network will be permanently retired. We recommend all wireless devices switch to using eduroam to prevent any interruptions when EECS-Secure is shut down.
If you are having trouble using eduroam, or cannot do something on eduroam that does work on EECS-Secure, please email us at help@eecs.berkeley.edu, or visit our Helpdesk in person at 395 Cory Hall.
For additional information about EECS-Secure retirement and the overall wi-fi roadmap, please see our previous announcement from April.
This afternoon at 1PM, we pushed a configuration change to the EECS border firewall which affects the firewall’s access to various configuration resources. This change was tested and we anticipate no effect; however please email help@eecs.berkeley.edu if you notice any of your machines or services suddenly become unreachable from outside the EECS network.
Beginning at 8:05 this morning, there is a partial wired network outage on the first floor of Cory Hall. The apparent cause is a failed switch; staff will arrive onsite this afternoon to investigate further and attempt repair.
We do not believe that wi-fi networks, or wired networks on other floors, are affected at this time.
Update 15:45: Network service was restored just prior to 3PM this afternoon. Please email help@eecs.berkeley.edu if you notice continuing network issues.
