Resolved as of 2019-11-13 07:00
Today between 1206 and 1212, EECS networks were isolated from the outside world due to an unanticipated routing protocol behavior during a reconfiguration related to our firewall replacement project. This has been corrected and there will be no further issues.
Staff are investigating intermittent disturbances in network traffic at or around the EECS border. We’ll provide updates here as we learn more.
Final Update 11/4 12:09:
This issue was caused by a DDoS or DDoS-style traffic which was overloading our firewall, which is near the end of its life. Using a number of active and passive mitigation techniques, we believe the impact of this traffic has been fully mitigated and there should be no further issues; the firewall has been stable since Friday morning. We are also accelerating the project already in the works to replace this firewall.
We’ve been notified of another impending PG&E power outage scheduled to begin Saturday evening, October 26; campus Co-Generated power should take over, similar to the last outage earlier this month (https://iris.eecs.berkeley.edu/news/resolved-incidents/potential-campus-power-outage/)
We are planning to keep essential services up and running, including networking, fileservice, web services (people.eecs and group project sites), DHCP, DNS, login.eecs, WINTERM, and lists.eecs (maillists). Some redundant systems may be powered down (e.g. cronus will stay up for DNS/NIS, but rhea may be shut down).
We encourage everyone to shut down all non-essential systems at the end of day today (Friday). Any reduction in power consumption will make it easier to keep other essential services running.
