There will be a power shutdown for Soda Hall on Tuesday August 29th, scheduled for 3 to 7 AM. The shutdown and short notice are due to an urgent need for the campus high voltage team to repair equipment which was damaged in June. It is also possible that the outage could be extended if difficult circumstances are encountered.
We have arranged with campus facilities to receive generator power for 288 and 290 Soda so that we can continue to provide IT services to the outside world while Soda is dark. As such, no interruptions to IRIS services outside Soda Hall are expected at this time. However, due to many electrical load variables it is possible that we may need to shut down some services without notice during the maintenance window.
Power to research server rooms 420A and 287 will be lost and the sysadmins of those rooms are coordinating a full system shutdown.
For sysadmins of machines in 340 Soda, you will also need to shut down your machines. We recommend doing so before midnight, or 2AM if you feel like cutting it close.

Tomorrow, 8/23, between 12-1PM we will be performing tests of our new border router (specifically the BGP links to campus).
We have two uplinks, and will use the secondary link for this test, so no network interruptions are expected. In the event there is a connectivity issue, the test will be aborted immediately.
Please contact help@eecs.berkeley.edu if you have any questions.

After a long preparation, we are almost ready to begin providing IPv6 service. We originally planned to be ready by the end of August, but due to various delays we are currently about one month behind schedule. Our remaining steps are:
* complete replacement of existing border router
* request IPv6 blocks from campus
* configure IPv6 routing
* begin providing IPv6 connectivity
We anticipate that in the best case scenario we may be ready for early deployments as soon as late September, although October may be a more reasonable estimate if further complications arise.
Our plan, once the routing core has been enabled for IPv6, is to start with small deployments on our backend infrastructure networks and also for research groups which have been waiting some time for IPv6. These initial deployments will be barebones “plumbing only” and likely will not include automatic IP address assignments (DHCP/SLAAC) or name services (DNS). When those services are ready, we will begin a large-scale deployment of IPv6 to the public production networks.
If you are interested in IPv6, please take a moment to fill out the survey linked here. This will help us gauge interest and let us know who to reach out to for the initial deployments.

The departmental dhcp server will be down for a needed reboot to activate changes delivered by some RHEL patches.
Though the scheduled downtime is 7:00am to 7:30am, we expect actual downtime to be less.

The departmental authenticating outgroup smtp server gateway.eecs will be down for a needed reboot to activate changes delivered by some RHEL patches.
Though the scheduled downtime is 7:15am to 7:45am, we expect actual downtime to be less.

The LDAP servers behind the load balancer for ldap.eecs.berkeley.edu will be upgraded tonight between 6pm and 8pm. Beginning at 6pm a final backup will be made of the data on the old servers, loaded into the new servers, and then the old servers will be retired. No service interruption is expected as the load balancer will be used to route requests to the right machines during the transition.
This is a change in both operating system and OpenLDAP software version. We have been testing the new servers for several months and do not expect any problems, but please inform help@eecs if you have any issues after the upgrade.
One enhancement is the addition of the memberOf overlay. This puts a new attribute (memberOf) in each person’s record to reflect LDAP groups they are members of, and is needed for some authorization situations.
Unix groups and automount maps are now also published in LDAP. Documentation is being prepared which will describe how to configure sssd on Unix/Linux machines to use these new OUs in LDAP instead of NIS.
