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.

EECS Website, FTP, Jabber, and Sympa Offline for Urgent SAN Maintenance

by

Due to some urgent maintenance to the SAN, the EECS Website, EECS FTP server, Jabber, and Sympa (mailing lists) services will be offline from 5:00 p.m. to 6:00 p.m. on Tuesday, September 23, 2008.

The servers hosting the aforementioned services lack redundant connections to the SAN which prevents them from remaining in service during the maintenance. We realize this is an unfortunate limitation and are procuring new hardware which will add the redundancy necessary to handle similar situations more gracefully in the future.

Our apologies for the short-notice and inconvenience.

Department Webserver Upgrade, Monday, Sep 15

by

On Monday, Sep 15 at 6pm, IRIS will be performing an upgrade of the department web service on www.eecs.berkeley.edu and www.cs.berkeley.edu. The service will be moved onto a new cluster of redundant hardware, and the server software will be upgraded to Apache 2.2 (from 2.0).

We expect no downtime, but web services might be unstable around 6pm, but should stabilize no later than 6:15pm.

Most people will not notice any change, except that the web server will be much faster. And while the old server was very reliable, the new cluster gives us an even more robust and flexible environment.

This upgrade pertains to all [research websites](https://iris.eecs.berkeley.edu/10-services/web-technotes.html#upgrade) that are hosted on this server.

The software upgrade will affect a small number of people who have put passwords on part of their personal website. We will be contacting those individuals directly by email to let them know [what they will need to change](https://iris.eecs.berkeley.edu/10-services/web-technotes.html#upgrade).

If you would like access to the new server in advance to test out your personal website, please contact help@eecs and we will send you the necessary information.

Windows file service outage on home/project today

by

There will be a brief (few seconds) CIFS outage at 6pm today. This will affect Windows clients and Samba users.

Most people won’t notice the brief outage, but there’s a possibility that some Windows applications with open files may get a bit confused. We recommend all affected users save any open files before 6pm and wait until a few minutes after 6pm to resume work.

The purpose of this brief outage is to resolve a problem that has prevented some Mac users from accessing our file servers. Once we have confirmed that problem has been resolved, a separate announcement will be made.

File Server Slowness

by

Access to EECS home directories on home.eecs was particularly slow for a while this morning. For users with mail or browser profiles in their home directories, this may have prevented their mail client or browser programs from functioning normally.

Access to project.eecs does not appear to have been affected.

Staff are investigating the cause. The likely culprit are slowdowns from a new backup combined with replication.

The symptoms disappeared at 9:30am on Tuesday, Sep 09. More should be known about the root cause by 9am Wednesday.
