Wireless network service

Wireless Networks Offline, Monday 1/5

by

As of about 11:51 AM: wireless networks are offline due to a power issue in one of the campus network core sites. Wired networks are unaffected and continue to operate normally. We will update again when we have more information about the status of the campus network core.

Update 13:36: Campus has begun restoring power to the network core using temporary connections, so we expect to see some wi-fi service resume. However, wi-fi may experience some continuing instability as the work to restore full power goes on.

Update 17:02: Power has been restored and network services should be fully available. There may be some late-night wi-fi disruptions as staff perform some cleanup work.

Please contact us at help@eecs.berkeley.edu if you have any questions.

Soda 2F Network Interruption, 9/18 10:41 AM

by

Networks on the second floor of Soda Hall were unavailable for approximately 5-10 minutes today beginning at 10:41 AM. This occurred due to a switch crash during troubleshooting a memory leak.

The network is now stable, but the memory leak issue still exists and requires further network disruption to resolve. We will be attempting to address this during tonight’s already-scheduled Soda Hall electrical shutdown.

Please contact us at help@eecs.berkeley.edu if you have any questions.

Network Instability, 8/31 9PM – 9/1 2AM

by

Portions of the EECS and campus networks experienced instability last night between 9PM and 2AM due to DDoS-like traffic directed at a system on the EECS network. This ended without intervention from network staff; we are investigating and remaining on standby in case this reoccurs.

Please contact us at help@eecs.berkeley.edu if you have any questions or notice any issues.

Jacobs Hall Network Maintenance, Tue. 8/12 10PM – Wed. 8/13 7:30AM

by

We will be performing Jacobs Hall network maintenance overnight from Tuesday, August 12th at 10PM to Wednesday, August 13th at 7:30AM. This maintenance is to replace the existing end-of-life router and switches with newer campus standard devices.

All wired and wireless networks in Jacobs Hall will be unavailable between 10PM Tuesday night and 7:30AM Wednesday morning. We expect all networks to be back online by 7:30AM.

Update: This work has been completed. Please contact us at help@eecs.berkeley.edu if you notice any network issues.

POSTPONED: Jacobs Hall Network Maintenance, Tues. Aug. 5 6AM

by

At 6AM on Tuesday, August 5th, we will be migrating the first set of Jacobs Hall subnet gateways to new router hardware. This is being done because the current hardware is end-of-life, and also as part of a project to refresh Jacobs Hall networks to the current campus standard.

The following networks will be affected:
– Jacobs Hall general-use wired network (169.229.62.0/24)
– Jacobs Hall wireless networks

During this maintenance, the networks above will be unavailable for a period of time. We expect all work to be complete by 7AM.

Update 8/4: We are postponing this maintenance due to ongoing troubleshooting of a fiber link issue. A new announcement will be made when this work is re-scheduled. Please contact us at help@eecs.berkeley.edu with any questions.

EECS Network Maintenance, Wed. Mar. 26

by

We will be performing various network maintenance activities throughout the day on Wednesday, March 26th during the previously announced Soda Hall 2nd floor power shutdown. We expect that most of our work will not affect wired and wi-fi network service, however there will be some brief outages as described below.

Between 12PM and 1PM on the 26th, the areas listed below will experience at least one interruption to network connectivity. We expect most of these interruptions to be under one minute in length, but some wi-fi service may be unavailable for 5-10 minutes.

  • BWRC (wired and wi-fi)
  • BiD in HMMB (EECS wired)
  • Soda Hall all floors (wi-fi)
  • Soda Hall 4F north side, 5F-7F (wired and wi-fi)

Update 15:44: This work has been completed and all networks are online. Please contact us at help@eecs.berkeley.edu if you notice any issues.

Campus Network Instability, Fri. Feb 7

by

We have been experiencing campus-level network instability since sometime around midnight, which is affecting the EECS and BWRC networks. Network team is investigating and working with the vendor to restore full network connectivity.

Update 2/11 6:41AM: The campus network team resolved these issues late Friday evening and our monitoring indicates that the network has been stable since. Please contact help@eecs.berkeley.edu if you notice any ongoing issues.
