Resolved Incidents

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.

Soda Hall Electrical Shutdown and BWRC Network Outage, 11/5 7PM

by

Our Facilities crew has received the new circuit breaker to be installed on the first floor of Soda (see previous IRIS News items for September 18 and September 8), and has scheduled the installation for the evening of Wednesday, November 5. As announced to Soda Hall occupants by the building manager via email, power to the building will be out between 7PM and 10:30PM, so building occupancy will not be allowed.

Since this outage is expected to be longer than the previous work, IRIS will be shutting down the department NetApp fileservers, and all systems that depend on them (such as webservers and login servers). Fileservers will be shutdown at 6:45PM; most other systems will be shutdown between 6PM and 6:30PM. Please shutdown any systems that depend on IRIS fileservice by 6:30PM.

We plan to keep dhcp.eecs and lists.eecs, the department mailing list server, online during this time. Redundant services such as Active Directory and LDAP will continue to be served from Cory Hall.

BWRC networks may be offline for a time during this shutdown, as they are dependent on Soda Hall.

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.

Soda Hall Electrical Shutdown and BWRC Network Outage, 9/18 7PM

by

Following up on the previous scheduled power outage, the electricians still need to try addressing the failed circuit breaker on the first floor of Soda, since first floor lights and Soda Hall main supply and exhaust fans remain off, and parts of the building are becoming unbearably hot due to lack of airflow.

Similarly to last time, Soda Hall will be completely without power beginning at 7PM. Please shut down your systems before 7PM on Thursday to avoid any issues. This includes all systems in the Soda 340 server room. Power is expected to be restored by 8:15PM.

We expect all IRIS services to remain available, due to a combination of battery backups and redundant servers in other buildings.

BWRC networks will be offline during this shutdown, as they are dependent on Soda Hall.
