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

|

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

|

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.

Network Border Maintenance, 6/20/17 7AM

|

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.

Soda Aggregation Router Upgrade, 5/2/17

|

We will be performing a software upgrade of the Soda Hall aggregation router at 6:30 AM on Tuesday, May 2nd. Wired and wireless networks in Soda Hall will be unavailable for 5-10 minutes while the router reboots. BWRC will also be cut off from the outside world during this time as its uplink is dependent on this router.

The Millennium research network will not be affected.

This upgrade is being performed to resolve certain bugs in the current software version so that we can move forward with our early-stage IPV6 deployment, which is currently targeted for this summer.
