Cory Hall Server Net Maintenance, 6/2/16 9PM

by

We will be performing maintenance on the Cory Hall restricted and server networks tonight at 9PM. Machines on the 128.32.244.0/25 and 169.229.60.128/25 networks (primarily, machines located in 165 Cory) will experience a brief loss of connectivity which we expect to last for less than 10 minutes.

The purpose of this maintenance is to migrate the default gateways for those subnets to a different router to address a possible traffic hairpinning issue. No reconfiguration will be necessary by sysadmins and there should be no visible lasting effect (other than reduced packet loss and/or latency on these networks).

Please contact help@eecs.berkeley.edu if you have any questions or concerns about this maintenance outage.

Jacobs Hall Wi-Fi Issues and Maintenance 3/14/16 10PM

by

The wireless networks in Jacobs Hall are currently malfunctioning due to a defect in the new code which was applied on Friday night. This defect has disabled the wireless network by preventing the APs from powering on fully. Staff are currently implementing a hardware based workaround which will bring the APs online for the afternoon.

We have identified a newer version that closes this particular defect, and confirmed with campus IST that it does work as expected. This upgrade will be applied tonight at 10PM and will involve a brief (~2 minute) downtime for the wired and wireless networks in Jacobs Hall.

Scheduled Storage Outage, Fri. 3/11/16 10PM

by

This Friday at 10PM we will be doing a software upgrade on the switch which provides connectivity for the EECS storage infrastructure. This upgrade is to address an issue with in-band management of the switch.

All storage services (home directories, project storage, etc.) will be briefly unavailable during the upgrade. Past experience suggests that this downtime will only last approximately five minutes. We strongly recommend that you save and close all open files in home and project spaces before 10PM on Friday. Machines with permanent NFS mounts may need to be rebooted after the maintenance is complete.

Please contact help@eecs.berkeley.edu with any questions or concerns.

BWRC Wi-Fi Maintenance, 3/3/16 7AM

by

We will be performing Wi-Fi upgrades at BWRC on Thursday morning to address a critical security vulnerability and also to upgrade the access points. The wireless network will be unavailable during this time and should be fully operational by 8AM.

The new access points will support 802.11ac with 80MHz channels, and will also provide increased coverage and signal performance.

If you have any questions about either of these upgrades, please email networks@eecs.berkeley.edu.

Wireless Maintenance – All Locations, 1/13/16

by

We are recalibrating the system which determines wireless AP transmit power. The procedure requires us to reset the radios several times, which will cause any client machines to disconnect.

We will make the changes separately on each frequency band to attempt to reduce interruptions to the wireless service.
