Wireless Network Outage on July 20 at 7:00AM

by

Wireless AP controllers will be upgraded with the production code on July 20 (Tuesday) at 7:00AM-8:30PM. I will reboot all Cisco AP controllers. I will schedule the wireless network downtime. You may experience that the wireless network will be down for about or less 20 mins for each building during 7:00AM-8:30AM. If everything goes ok, the total hours will take less than 1.5 hours. This upgrade will affect wireless users in Soda, Cory,Citris and BWRC. During this time, the wired network will still work.

If you have questions, please contact with networks@eecs

Email Service Migration to CalMail

by

IRIS is beginning the process of migrating Email service to CalMail. This will be a multi-step process and is expected to take seven months to complete. At the end of that time, all users who receive email at an @eecs, @cs, or @erso address will do so using the CalMail service for department domains.

A list of Frequently Asked Questions related to the migration effort is being maintained, which will be updated with current information. It contains answers to many of the who, what, why, when, and how questions. If you have additional questions, please send them to help@eecs.

FAQ: https://iris.eecs.berkeley.edu/15-faq/CalMailMigrationFAQ.html

The first step of the process took place Tuesday 6/29/2010, at which time all incoming email began to be routed through the CalMail (MX) servers and then delivered to IRIS. No action was required on your part at that time and there should be no significant impact on email service. There will be some differences in behavior, however, such as additional headers applied by the CalMail Spam servers and a limit imposed on email larger than 50MiB. More detail is in the FAQ.

You will be contacted before any actions are required or taken on your part with respect to the migration of your email. These communications will happen throughout the seven month period.

IMAP Service down briefly

by

Starting at around 1AM, staff began to receive reports of problems with expunging or deleting messages from inboxes on imap.eecs. This problem seems to have affected all users regardless of the choice of e-mail client, including the web client.

At approximately 2AM, the problem appeared to have degraded to the point that e-mail clients were no longer able to successfully connect to imap.eecs.

At approximately 2:20AM, service was restored.

It is not clear at this time what the cause of the outage was or whether service was restored by staff intervention or by automatic system reboot after a crash.

If you continue to have problems accessing your mail via imap.eecs, please contact the [IRIS Helpdesk](https://iris.eecs.berkeley.edu/help)

Network core maintenance

by

I will be replacing two 10Gbit line cards in the Soda Hall core router. I will replace one card today, and one tomorrow.

We’ve already replaced similar line cards in the EECS border and Cory Hall routers without incident. The Soda router reconfiguration is slightly more complex, but due to redundant connections and routing, no discernible connectivity disruption is expected.

The vendor confirmed that the current line cards contain faulty hardware and provided replacements. The IRIS network suffered several outages due to this bug, which typically only appears after 6-9 months of operation.
