Soda Hall Power Shutdown, Tues. 8/29/17

by

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.

Network Border Testing, 8/23/17

by

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.

IPv6 in EECS: Finally Coming Soon

by

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.

Network Border Maintenance, 6/20/17 7AM

by

We will be performing maintenance at the EECS network border at 7AM on Tues. June 20th. There may be a brief loss of connectivity between EECS and outside networks at this time.

If a loss of connectivity occurs, we expect it will likely last less than five minutes. In this event, the following traffic paths would be interrupted:

* EECS to campus networks
* EECS to Internet
* EECS to Millennium research

The following will not be affected:

* Traffic within EECS networks
* Millennium research connectivity to campus/Internet
* Science DMZ
* Private networks in the EECS DMZ (CESR, DETER)

“EECS” in this case refers to all wired and wireless production nets, all server and machine rooms, and all private networks not otherwise mentioned above.

Please contact help@eecs if you have any questions about this change or concerns about scheduling.

Campus Wireless Networks Unavailable, 6/7/17

by

Campus wireless networks (AirBears2, eduroam, CalVisitor) were unavailable for a period this morning due to an issue with authentication load balancers. At the direction of campus wifi admins we have reconfigured these networks to bypass the load balancers for now.

All networks are once again available for use within EECS.
