An attempt at adding a new switched link in the network core resulted in a broadcast storm which crippled the EECS network between approximately 5 and 6 PM this evening. The maintenance was rolled back and the network was allowed to stabilize. We will reattempt this maintenance in the future after we have analyzed the data gathered to determine what went wrong.

Jabber server misbehaving
Yesterday (April 29th) we installed the latest version of the Openfire server software that powers the department’s XMPP/jabber server. The new version seems somewhat buggy and has hung a couple times today. We are investigating, and will roll back to the previous version on Friday May 1st if we cannot determine the cause.

Department Webserver Upgrade, April 28th
On April 28, 2015, the department webserver www.eecs.berkeley.edu (and www.cs.berkeley.edu, as well as all the project websites that IRIS hosts) will be migrated to new, faster hardware. As part of this upgrade, we will also be upgrading the version of the Apache HTTP server software to the current branch, Apache 2.4. This is considered the current best version and contains [numerous improvements over the 2.2 branch we are currently running](http://httpd.apache.org/docs/2.4/new_features_2_4.html).
Unfortunately, [there are some changes in syntax or behavior](http://httpd.apache.org/docs/2.4/upgrading.html) that will affect people who have their own websites. The owners of any web site which may be affected by this change will receive a direct email later today with the subject “Action Needed: Update your .htaccess files.” This email will list the specific file(s) you need to check and will include a link to some documentation on the most common changes that will be needed.
This documentation is now [up on our website](https://iris.eecs.berkeley.edu//10-services/web-technotes.html#upgrade24) .

2015 Wi-Fi Upgrade – Much Excite!
We are pleased to announce a project to fully upgrade the EECS Wi-Fi infrastructure. The community has borne with us through years of wireless issues, including poor coverage, frequent disconnects, inability to connect, and others. After working through a sizable backlog of technical debt, we’re finally ready to get to work on a solution.
Summary of main points:
* We will be upgrading equipment as well as redesigning our coverage plan
* Adding 802.11ac support and increasing density in the 5GHz band
* Phase I: Survey – April through May
* Phase II: Install – June through September (possibly October, contingent on unforeseen delays) [Update: please see timeline post below for live details]
* Engineers will need access to all spaces (offices, labs, classrooms, etc.) during both phases of the project (we cannot ensure good coverage for any area that is not surveyed properly!)
Beginning this week, engineers will be performing detailed surveys of Soda, Cory, and Sutardja Dai Halls in order to fully understand each space and its uses. Our current deployment was designed during a much earlier time in Wi-Fi’s history and was never intended to cope with the number of wireless devices in use today or the way in which we use them; it also includes some oddities such as access points being mounted in hallways where they have trouble reaching into offices and labs. This is being taken into account and access points will be moved into the areas where they will be used, which will require our engineers to fully explore all classrooms, labs, offices, and conference rooms. In addition to reevaluating where and how we place access points, we will be increasing density (more APs) and upgrading to newer and more powerful models which support 802.11ac.
This project is broken up into two main phases. As mentioned above, the survey phase is beginning this week, and will consist of detailed walkthroughs of all wireless locations. The second phase, which will begin after the current semester is concluded, will involve contractors running cables and installing the new access points.
The current wireless deployment will remain online until the new APs are fully installed, at which point we will switch over.
To ensure that our new design provides complete coverage, our engineers will need access to all spaces within EECS, including individual offices. We will do our best to work around busy people and spaces, but if possible please try to take a moment for us when we come around. Remember: we cannot ensure good coverage for any area that is not surveyed properly.
Please contact help@eecs.berkeley.edu with any questions or concerns. We appreciate your patience with the wireless network as of late, and look forward to providing a much higher level of service.
