cronus.cs remains down after neighborhood power outage

by

A power outage to Soda Hall which began around 12:30pm on June 21, 2017 took out many IRIS services.

At about 3:00pm, power was restored to Soda Hall and staff are bringing up network equipment now. The power conditioner in the main Soda machine room had problems recovering, and campus electricians required additional time to get it back online. Our IRIS staff then were able to begin bringing infrastructure online, including dhcp, fileservice, DNS, etc.

By 6:50pm, most IRIS services were restored.

cronus.cs, one of our DNS and NIS servers, remains down at this time. This may cause delays or timeouts for various machines and services.

New Procedure for Changing Unix Passwords and Shells

by

A new web page has been deployed to allow IRIS account holders to change their Unix password or shell. This page replaces the old procedure of logging into the server passwd.cs.berkeley.edu.

The new page is available now [on the IRIS website](https://iris.eecs.berkeley.edu/selfserve/nispasswd/). You may authenticate to this page using either your EECS Windows / LDAP password, or by using your CalNet passphrase.

Please direct any questions or comments to the IRIS helpdesk at help@eecs.berkeley.edu.

Network Border Maintenance, 6/20/17 7AM

by

We will be performing maintenance at the EECS network border at 7AM on Tues. June 20th. There may be a brief loss of connectivity between EECS and outside networks at this time.

If a loss of connectivity occurs, we expect it will likely last less than five minutes. In this event, the following traffic paths would be interrupted:

* EECS to campus networks
* EECS to Internet
* EECS to Millennium research

The following will not be affected:

* Traffic within EECS networks
* Millennium research connectivity to campus/Internet
* Science DMZ
* Private networks in the EECS DMZ (CESR, DETER)

“EECS” in this case refers to all wired and wireless production nets, all server and machine rooms, and all private networks not otherwise mentioned above.

Please contact help@eecs if you have any questions about this change or concerns about scheduling.

Campus Wireless Networks Unavailable, 6/7/17

by

Campus wireless networks (AirBears2, eduroam, CalVisitor) were unavailable for a period this morning due to an issue with authentication load balancers. At the direction of campus wifi admins we have reconfigured these networks to bypass the load balancers for now.

All networks are once again available for use within EECS.
