Soda Hall Scheduled Power Outage, January 4th

by

There is a full-building power outage for Soda Hall scheduled for Sunday, January 4th from 7AM to 2PM. During this time the building will be completely powered off and entrance to the building will not be allowed. This is to facilitate electrical work for the Jacobs Hall construction project and is not related to the EECS-wide network outage scheduled for Saturday, January 3rd.

We have arranged for reserve power to be provided to the network and server rooms in 288, 290, and 420A Soda, such that department and research infrastructure and services will remain online and available to users outside Soda Hall.

We recommend powering off all equipment such as desktop computers ahead of time to prevent any issues caused by unexpected power loss. Additionally, any sysadmins hosting equipment in machine rooms other than 288, 290, and 420A will need to power their machines down in advance of the outage.

Should you need access to the building during the outage (for example, you are a sysadmin who would like to take advantage of the downtime to perform deferred maintenance), please email Miles Bianchi (miles.bianchi@berkeley.edu) for consideration by the Safety Committee. This access will only be granted for special cases.

As an early heads up, there is another, longer outage tentatively scheduled for Friday, March 27th from 6AM to 6PM, during which the Jacobs Hall electrical hookups will be completed. More details will be communicated as the date gets closer.

As always, we apologize for any and all inconvenience caused by this outage, especially given its close proximity to the previously scheduled network maintenance. If you have any questions or concerns, please contact Derek (dcalderon@berkeley.edu) for IT issues or Miles (miles.bianchi@berkeley.edu) for facilities or safety issues.

EECS Network Scheduled Outage on Jan. 3-4 2015

by

There will be a full scheduled outage of the EECS network from 10AM – 8PM on Saturday, January 3, 2015. There may be additional contingency outages on Sunday the 4th, but we are unable to confirm the need for additional outages at this time. During this window, the entire EECS network will be offline as we transition to our new routing core.

Expected service impacts:

– Internet connectivity will be unavailable on all EECS networks
– All EECS Wired* networking will be offline or unreliable
– All EECS Wireless** networks will be unavailable (the networks will continue to be visible in some locations, however the underlying transit networks will be offline)
– The BWRC will be isolated from EECS and unable to access the Internet or non-BWRC-hosted resources
– EECS hosted services (such as NFS project space and home directories) will be unavailable

We apologize for any inconvenience that this maintenance will cause. Please contact help@eecs.berkeley.edu with any questions or concerns.

Thank you,
EECS/IRIS Network Group

*EECS Wired locations include Soda, Cory, and Sutardja Dai Halls, and the BWRC

**EECS Wireless locations include Soda, Cory, Sutardja Dai, Calvin, and Blum Halls, as well as the Sibley Auditorium, certain areas of the Hearst Memorial Mining Building, and the BWRC

Scheduled Maintenance for Wireless Authentication Services

by

On Wednesday, November 26th at 4-5PM we will be installing updated TLS certificates on our primary wireless authentication (RADIUS) server and on the EECS-Guest web authentication portal. Due system redundancy, no outages are expected, except for a possible brief interruption in EECS-Guest authentication. Existing connections will not be lost, but there may be a short period in which users cannot initiate new connections to EECS-Guest. In this event, we recommend the use of CalVisitor until EECS-Guest is responding again.

Scheduled Maintenance for Wireless Authentication Server

by

On Wednesday, November 5 at 1PM, we will be performing scheduled maintenance on the primary wireless authentication (aka RADIUS) server, etips1.eecs. The maintenance window is scheduled to end at 2PM.

EECS-Secure will not be affected during the maintenance, as the secondary server will be available to process authentication requests. However, the secondary server is currently unable to process requests for EECS-Guest, and as a result EECS-Guest will NOT be accepting new connections. Existing sessions should not be disconnected, but any new EECS-Guest sessions will fail to authenticate during the maintenance. We recommend that visitors use CalVisitor as a workaround during this time.

Please direct any questions, comments, or concerns to help@eecs.berkeley.edu.

Unscheduled Wireless Outage, HMMB and Sibley Auditorium

by

We are currently experiencing an unscheduled wireless outage in some locations in the Hearst Memorial Mining Building, as well as in the Sibley Auditorium in the Bechtel Engineering Center. The outage is due to a campus zone router crash, and many campus-managed wired and wireless networks are also affected.

IST/Telecom is working to restore service and we will update this news item when service has been restored. We apologize for any issues caused by this interruption.

Brief Scheduled Outage for EECS Wireless

by

There will be a brief scheduled outage of all EECS wireless networks on this Friday, September 19th, in order to perform a minor configuration change which will require a reboot of the wireless controllers. The maintenance will begin at 6:30AM and is expected to be complete by 7AM.

This is scheduled to coincide with a related maintenance being performed by IST on their wireless controllers, which serve the rest of campus. Information on the IST scheduled outage can be found at ucbsystems.org, CMR #3214.

This outage will affect all wireless networks (including AirBears) in all EECS locations: Soda, Cory, Sutardja Dai, and Blum Halls, as well as the Calvin Lab and the BWRC, and some areas of the Hearst Memorial Mining Building.

For questions, concerns, or comments, please contact help@eecs.berkeley.edu.

Thanks,

EECS Wireless Network Upgrades, Outages, and Changes

by

On Saturday, August 30th, between 11AM and 6PM, we will be replacing the EECS wireless controllers with newer models. As a result, all wireless networks in all EECS locations will be offline during the upgrade. The wired network will not be affected.

Networks affected: EECS, EECS-Secure, EECS-Open, EECS-Guest, EECS-Robonet, EECS-Viper, 326capture, 540capture, AirBears, AirBears2, attwifi.

Locations affected: Soda Hall, Cory Hall, Sutardja Dai Hall, Calvin Lab, Blum Hall, Sibley Auditorium, Hearst Memorial Mining Building

Additionally, the following changes are being made to EECS wireless network offerings:

EECS: this network will be renamed to EECS-PSK and the security protocol will be changed from WEP to WPA2-PSK, which is much more secure. The preshared key (password) used to access the network will not change.

EECS-Open: this network will no longer be offered.

326capture and 540capture: these networks are being merged into a single network called EECS-Capture. The preshared key will not change.

Simons: the Simons SSID will no longer be offered.

Please direct any questions or concerns to help@eecs.berkeley.edu.

UPS Maintenance in SDH 158

by

At 11 AM today we will be replacing batteries and performing maintenance on a faulty UPS located in our primary server and network room for Sutardja Dai Hall. No service interruptions are expected. However, in the event of a failure, there may be a ~5 minute loss of wired and wireless networking in Sutardja Dai Hall, as well as a loss of the NetApp network file storage for the EECS Instructional Labs. The maintenance is expected to last for approximately one hour, but two have been allotted in case of complication.
