Approximately 4AM this evening, we lost contact with the access switch in the Nanolab on the 6th floor of Sutardja Dai Hall. We presume the network to be down at this time, and network staff will begin diagnosis as soon as they arrive onsite. This should affect users in the 6th floor area of the Nanolab only, as the rest of SDH uses separate switches.

On Wednesday evening at 6PM, we will be performing maintenance on the EECS firewall in order to to reinsert the primary device (which failed during the January power maintenance) into the production cluster. Per the vendor, no interruption in service is expected; however, in the event of unforeseen complications Internet connectivity may be lost to the department for some time.

There will be another emergency scheduled maintenance tonight at 7PM. This window is scheduled to close at 10PM but the network will be available earlier if all goes well. The wireless network in all locations except BWRC will be unavailable during reconfiguration. Wired networking also will be briefly (less than ten minutes) unavailable for a routing change. We believe these steps will take us closer to fully eliminating the current traffic issues.

We apologize for the massive inconvenience and fully intend to have these issues resolved before the start of the semester.

We will be performing emergency network maintenance tonight at 7:30-10. The network will not be completely unavailable during this time, but the wireless network as well as the wired network in some buildings may periodically go offline. It is our hope that we can use this time to gain insight into the ongoing network issues and help with a resolution before the semester begins.

We expect that the wireless may be down for 20-60 minutes, and that several segments of the network will go offline for periods of 5-10 minutes during the window.

There is a full-building power outage for Soda Hall scheduled for Sunday, January 4th from 7AM to 2PM. During this time the building will be completely powered off and entrance to the building will not be allowed. This is to facilitate electrical work for the Jacobs Hall construction project and is not related to the EECS-wide network outage scheduled for Saturday, January 3rd.

We have arranged for reserve power to be provided to the network and server rooms in 288, 290, and 420A Soda, such that department and research infrastructure and services will remain online and available to users outside Soda Hall.

We recommend powering off all equipment such as desktop computers ahead of time to prevent any issues caused by unexpected power loss. Additionally, any sysadmins hosting equipment in machine rooms other than 288, 290, and 420A will need to power their machines down in advance of the outage.

Should you need access to the building during the outage (for example, you are a sysadmin who would like to take advantage of the downtime to perform deferred maintenance), please email Miles Bianchi (miles.bianchi@berkeley.edu) for consideration by the Safety Committee. This access will only be granted for special cases.

As an early heads up, there is another, longer outage tentatively scheduled for Friday, March 27th from 6AM to 6PM, during which the Jacobs Hall electrical hookups will be completed. More details will be communicated as the date gets closer.

As always, we apologize for any and all inconvenience caused by this outage, especially given its close proximity to the previously scheduled network maintenance. If you have any questions or concerns, please contact Derek (dcalderon@berkeley.edu) for IT issues or Miles (miles.bianchi@berkeley.edu) for facilities or safety issues.

There will be a full scheduled outage of the EECS network from 10AM – 8PM on Saturday, January 3, 2015. There may be additional contingency outages on Sunday the 4th, but we are unable to confirm the need for additional outages at this time. During this window, the entire EECS network will be offline as we transition to our new routing core.

Expected service impacts:

– Internet connectivity will be unavailable on all EECS networks
– All EECS Wired* networking will be offline or unreliable
– All EECS Wireless** networks will be unavailable (the networks will continue to be visible in some locations, however the underlying transit networks will be offline)
– The BWRC will be isolated from EECS and unable to access the Internet or non-BWRC-hosted resources
– EECS hosted services (such as NFS project space and home directories) will be unavailable

We apologize for any inconvenience that this maintenance will cause. Please contact help@eecs.berkeley.edu with any questions or concerns.

Thank you,
EECS/IRIS Network Group
