Description: This Thursday, IST will be upgrading the Operating System on both Wireless Control Servers and on many of the Wireless Access Managers throughout campus.

This outage will affect ALL AirBears locations throughout campus and surrounding areas. During the upgrade process, affected networks will be unavailable, and currently attached clients will be required to reauthenticate.

Please note that the maintenance window for this outage is one and one half (1.5) hours. The affected subnets should be back on-line within forty minutes of the initial outage, but a larger window has been allocated to allow for unforseen challenges.

Brief Interruption of Some IRIS Services

by

The department website, Jabber and Sympa services were briefly interrupted this morning due to an issue with the cluster that provides them.

Each service was unavailable for a few minutes between 10:00 a.m. and 10:30 a.m. as the server cluster they run on was restarted. Restarting the cluster was necessary to alleviate a deadlock in the clustered file system used by the services.

My apologies for any inconvenience this has caused, I’m looking into how to avoid this situation in the future and bring more stability to the cluster.

Urgent Patch for Windows systems

by

Microsoft has just released an emergency out-of-band update to address remote code exploits in Windows versions 2000/XP/2003/vista/2008.

Please update Windows systems as soon as possible as exploits are already in the wild. Due to the release of this update, you may experience slow responses from the Windows Update service.

While the EECS firewall blocks traffic on the affected ports, all affected systems – especially mobile systems that come and go from from the EECS network such as laptops – should apply this update as soon as possible.

If you have not already done so please make sure you have installed KB958644 on all your Windows hosts.

This is the best description of the vulnerability I have found so far; http://www.intelliadmin.com/blog/2008/10/smb-vulnerablity-found-emergency-patch.html

IMAP access is currently off while staff are trying to resolve the issue. IMAP service will be restored as soon as possible.

Several background IMAP processes have been crashing resulting in the observed behavior. Currently the IMAP server is being patched.

Unexpected Outage of Dept. Website, FTP, and Mailing Lists

by

Due to some necessary maintenance to some SAN hardware, the department’s website, FTP server, and mailing lists experienced brief outages this evening beginning around 6:24 p.m.

The website and FTP server were only offline for about six minutes, but mail sent to lists handled by lists.eecs.berkeley.edu (Sympa) during the outage may have been delayed up to 45 minutes. I apologize for any inconveniences this may have caused.

The server hosting the department web and FTP services along with the one hosting the database used by Sympa went offline when they unintentionally lost their connection to the SAN during maintenance. The maintenance was last-minute and shouldn’t have caused any disruption, but it didn’t quite go as planned.

Hardware has arrived to allow us to make redundant connections to the SAN for these services which will make them more resilient in future situations like this one. We plan to have the hardware installed and in use soon.

Wireless Network Slowdowns

by

Some locations for EECS supported wireless services were very slow or disrupted due to a controller issue. The areas affected were HMMB, BWRC, Brewed Awakenings and some of the upper floors of Soda. A controller reboot appears to have solved the issue.
