There was an unexpected impact to the wired and wireless networks at approximately 4pm causing significant packet loss. IRIS staff has isolated the problem and is in the process of restoring impacted services. A configuration change by IT staff to the network was the enabler that allowed hosts from the server room to flood the network.

will monitor email to help@eecs for network problem reports.

10am-11am, Cory Hall 2nd floor wired network migration
======================================================
Any activated port cables id that have not migrated from the 47 subnet
by Wednesday December 26, 2012 will be migrated then. Further
information is available at:

11am-12pm, BWRC campus link switched from Comcast to AT&T
=========================================================
The circuit that connects the Berkeley Wireless Reserach Center (BWRC)
will be switched from the current 100Mb Comcast link to a 1Gb AT&T
link. We expect the downtime will take less than 5 minutes, but have
scheduled an hour maintenance window for testing puroses and
unexpected problems (in the event of which we can switch back to the
Comcast link).

12pm-3pm, Firmware upgrade for EECS Wireless network
====================================================
New firmware will be applied to the EECS wireless network devices.
This will require a rolling reboot across all four wireless
controllers. You may experience wireless outages during this time,
however the wired network will be available.

Please report the issues to networks@eecs if you experience network
problems after the maintenance window is complete or if you have any
other concerns.
