Wired Network Partial Outage, SDH Floors 1-4 on 7/7/15

There was a partial network outage today for floors 1-4 of Sutardja Dai Hall; the outage affected any machine on the 128.32.156.0/24 subnet which was using an address between 128.32.156.64 and 128.32.156.127 (25% of all hosts on these floors). Hosts in this address range had EECS connectivity but were unable to reach campus or the wider Internet. Wireless service in some areas was likely also influenced, as the wireless access points use this subnet for their connectivity.

Through collaboration with IST-NOS we learned that a typographical error was made while adding a new route in the campus datacenter at Earl Warren Hall, causing traffic destined for these 64 hosts to land in Warren rather than Sutardja Dai. The erroneous route was pulled and traffic is now being routed correctly.

If you continue to notice any issues, please email help@eecs.berkeley.edu.
