Network Outage for Sutardja Dai, Blum, Calvin Halls

by

As of 2:21 pm, networking for Sutardja Dai, Blum, and Calvin Halls is offline. Staff are en route to campus for further investigation.

Update: network connectivity was fully restored at 6:00PM when certain hosts which were causing instability were removed from the network. We will follow up tomorrow with the sysadmins of these hosts to try and prevent future incidents.

Wi-Fi Outage, Cory and Sutardja Dai Halls

by

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

by

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.

IPv6 Coming to EECS Wi-Fi This Weekend (Feb. 15-16)

by

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.

EECS-Secure Authentication Certificate Updated

by

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.

Intermittent Network Trouble at EECS Border

by

Staff are investigating intermittent disturbances in network traffic at or around the EECS border. We’ll provide updates here as we learn more.

Final Update 11/4 12:09:
This issue was caused by a DDoS or DDoS-style traffic which was overloading our firewall, which is near the end of its life. Using a number of active and passive mitigation techniques, we believe the impact of this traffic has been fully mitigated and there should be no further issues; the firewall has been stable since Friday morning. We are also accelerating the project already in the works to replace this firewall.

Potential Campus Power Outage

by

We have been alerted to possible PG&E power outages due to fire danger, and that campus power may be shutdown at some point over the next 2-3 days. If we receive notice of imminent shutdown, we will work to safely shutdown our NetApp fileserver and other critical infrastructure systems; this may occur on very short notice.

We will endeavor to update this News item as we receive any updates.

We recommend you proceed with shutting down any non-essential machines in advance, e.g. shutting down workstations at the end of the work day.
