September 1, 2020 by Lars Rohrbach

Summary

This announces the upcoming change to the firewall ruleset for the 8th floor of Berkeley Way West (BWW) on the 128.32.175.0/24 network.

This change is to help facilitate moving all IRIS networks to the campus Palo Alto firewall infrastructure. Also, going forward, emailed requests for BWW firewall exceptions will no longer be needed. The standard IRIS network registration forms will be utilized to make web servers at BWW available to the outside Internet.

Soda Hall Power Shutdown Tuesday 8/18 8am-8pm

August 12, 2020 by Derek Calderon

On Tuesday, August 18th, Soda Hall building power will be shutdown from approximately 8am to 8pm for required facilities work. There will also be sporadic brief outages to various IRIS services between 9am and 2pm due to network maintenance.

Our primary datacenter and network core will receive backup generator support and we generally expect all services to remain online throughout the day. However, we are taking the opportunity to perform a number of network maintenance items which would have otherwise necessitated multiple outages later in the year.

As a result there will be multiple brief interruptions to various services including NetApp file servers, DHCP and DNS service, and the login.eecs and winterm terminal servers. We expect each individual interruption will last for less than five minutes, and this work will be performed between 9AM – 2PM. This post will be updated when all network maintenance is complete.

After network services are fully restored, sysadmins may need to reboot their systems, restart/remount nfs file systems, etc. to get fully back online.
