EECS was without Internet connectivity from 8:06 to 9:13 AM this morning due to a firewall issue. The then-primary firewall appears to have hung in a manner that prevented the backup from taking over until network staff arrived onsite and manually intervened.

During the outage, users and machines on the EECS network were unable to access the Internet, and Internet users were unable to access EECS resources or the EECS Web site.

We are working to determine the cause of the issue as well as ways to mitigate similar cases in the future. We are also in the process of constructing an out-of-band management infrastructure to reduce time to repair in outage situations. No further interruptions are expected at this time.

If you continue to experience network issues, please email help@eecs.berkeley.edu or visit our helpdesk at 395 Cory Hall.
