Network Outage, 6th Floor SDH Nanolab

by

Approximately 4AM this evening, we lost contact with the access switch in the Nanolab on the 6th floor of Sutardja Dai Hall. We presume the network to be down at this time, and network staff will begin diagnosis as soon as they arrive onsite. This should affect users in the 6th floor area of the Nanolab only, as the rest of SDH uses separate switches.

Network Maintenance – Soda 5th Floor

by

We plan to failover to the backup uplink for the fifth floor of Soda Hall in order to troubleshoot a network issue. This action will be taken on February 3 around 6:00PM and it should take less than 5 minutes. No service interruption is expected, but in the event of a failure there may be a brief (5 minute) outage for some areas of the fifth floor. The failover will be complete by 6:15PM; if you are experiencing an outage after this time please email help@eecs.berkeley.edu.

Emergency Maintenance Part Deux TONIGHT 1/15 7PM

by

There will be another emergency scheduled maintenance tonight at 7PM. This window is scheduled to close at 10PM but the network will be available earlier if all goes well. The wireless network in all locations except BWRC will be unavailable during reconfiguration. Wired networking also will be briefly (less than ten minutes) unavailable for a routing change. We believe these steps will take us closer to fully eliminating the current traffic issues.

We apologize for the massive inconvenience and fully intend to have these issues resolved before the start of the semester.

Emergency Network Maintenance TONIGHT 7:30PM

by

We will be performing emergency network maintenance tonight at 7:30-10. The network will not be completely unavailable during this time, but the wireless network as well as the wired network in some buildings may periodically go offline. It is our hope that we can use this time to gain insight into the ongoing network issues and help with a resolution before the semester begins.

We expect that the wireless may be down for 20-60 minutes, and that several segments of the network will go offline for periods of 5-10 minutes during the window.

Ongoing Wireless Network Issues

by

We are currently experiencing worse-than-normal issues with the wireless network including inability to connect, random drops, increased latency, and reduced throughput. We believe we have an idea of the cause and will be working to clear things up over the next couple of days.

As always, we apologize for all inconveniences caused by the network’s performance.
