AirBears Abatement, August 14th 2015

by

At the end of the day on August 14th, the legacy AirBears wireless network will be permanently deactivated in favor of AirBears2, eduroam, and CalVisitor. To minimize interruptions, please make sure you are already switched over to one of these newer networks. If you have any trouble connecting, or are unsure which network to use, please visit http://ist.berkeley.edu/airbears or the EECS Helpdesk in 395 Cory Hall.

The original announcement from campus network services is included below. For updated information, please see ucbsystems.org, CMR# 3975.

—

After many years of faithful service the AirBears wireless network is being discontinued. After August 14th access to the UC Berkeley networks and Internet will no longer be available through this SSID.

Current students, staff, faculty, and affiliates who have not already done so, are invited to create a wireless key and use the AirBears2 wireless network. AirBears2 provides full campus connectivity without the redundancy of a login portal after initial configuration.

Visitors are welcome to connect using the CalVisitor wireless network, which provides Internet and basic campus connectivity without the necessity of a guest account.

Details on available WiFi Network Services and how to connect to them is available here:

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

by

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.
