Intermittent Network Trouble at EECS Border

by

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.

Oct 26 Planned Power Outage

by

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.

NetApp archive backups not working

by

When fileservice was restored after the PG&E outage last Friday, the part of the service that handles backups became non-functional. Staff are working to restore backup service as soon as possible.

Snapshots remain functional and available, providing easy access to file versions from the last 7 days. Older archive backups, from before October 9, also remain available. The broken archiving process means that backups after Oct 9 will not be available.

We make nightly copies of current fileserver data to our Disaster Recovery (DR) site at the San Diego Supercomputing Center (SDSC). This mirror of current data remains operational, and is not affected by the archive process failure.

Potential Campus Power Outage

by

We have been alerted to possible PG&E power outages due to fire danger, and that campus power may be shutdown at some point over the next 2-3 days. If we receive notice of imminent shutdown, we will work to safely shutdown our NetApp fileserver and other critical infrastructure systems; this may occur on very short notice.

We will endeavor to update this News item as we receive any updates.

We recommend you proceed with shutting down any non-essential machines in advance, e.g. shutting down workstations at the end of the work day.

Extreme Slowness for some EECS Services

by

Our VMWare infrastructure is undergoing a RAID reconstruction, and a number of EECS services are being impacted by this, resulting in such slowness that some services are inaccessible.

Impacted servers and services may include:

  • winterm.eecs
  • repo.eecs
  • http://cusg.eecs.berkeley.edu
  • gateway.eecs

We apologize for the interruption of service, and are working to restore all services to normal levels.
