Anonymous ftp access ending May 1, 2024
For many years the Department has operated an anonymous ftp server at ftp.eecs.berkeley.edu and ftp.cs.berkeley.edu. Before web sites, this was how software and papers were distributed to the public. Since web sites are the preferred way to distribute digital assets these days, no new content has been published on our ftp servers for over a decade. We will be ending support for anonymous ftp access effective May 1, 2024. After that time, the current contents of our ftp archive will continue to be made available via a web page at https://ftp.eecs.berkeley.edu and https://ftp.cs.berkeley.edu/.
Update: May 1, 1pm: The ftp server has been shut down. The replacement web page is up at https://ftp.eecs.berkeley.edu
NetApp Fileserver Maintenance, Saturday March 30, 2024
We are scheduling a NetApp ONTAP upgrade, to update our NetApp fileserver, from 8am to 12pm on Saturday, March 30, 2024.
All Home directories and Project shares (CIFS/SMB and NFS) may experience disconnection during the update that may cause data loss on active, open files. Please close your open files and save them before Saturday Morning. Services (e.g. webservice) that depend on this storage will also be temporarily down or unresponsive.
When maintenance is completed, NFS clients should automatically resume normal operation, but a reboot should help if they don’t. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.

Between 11AM and 5PM on Friday, March 29th, we will be replacing the access switches which provide wired network connectivity on the 1st floor of Cory Hall (including the mezzanine) and the 2nd floor of Soda Hall.
Wired networks in these locations will experience various interruptions during this time. Most of these interruptions will be brief (<30 seconds), but some cables on Cory 1F/1M will be down for an extended period of time (over an hour). Wireless networks will not be affected.
Primary networking in the server rooms (165 Cory, 287-290 Soda) will not be affected by this work. The exception is the floor boxes in those rooms, which will be affected.
Update 3/29 15:41: This maintenance has been completed and all networks are back online. Please email help@eecs.berkeley.edu if you notice any ongoing network issues.
Soda and Cory Network Maintenance, 3/16 6:30AM
On Saturday, March 16th, at 6:30AM, we will be performing an HA failback on some network switches in order to restore full operation after Wednesday’s electrical issues.

- Soda 4F (north side only)
- Soda 7F
- Cory 1F
- Cory 5F
Update 3/16 06:44: This work has been completed and all networks are back online. Please contact us at help@eecs.berkeley.edu if you notice any issues.

On Saturday, March 16th, between 11AM and 1PM, we will be replacing the network switch which provides wi-fi service for the first and second floors of Soda Hall. Wi-fi networks on these floors will experience some interruptions during this time.
Update 3/16 11:57: This work has been completed. Please email help@eecs.berkeley.edu if you have any network connectivity issues.
Various Network Outages, Wed. 3/13
We have experienced some scattered network outages due to an apparent power issue, beginning this afternoon at 12:40. Networks in the following areas are known to have experienced an outage:
- Cory 1F wired
- Cory 1F and 5F wi-fi
- Soda 4F and 7F wi-fi
- Sutardja Dai 2F, 3F, 4F wi-fi
- SDH Nanolab 3F-4F wi-fi
Wired networks recovered approx. 12:47; wi-fi should have largely recovered by 13:00, but may still experience some interruptions as the electrical issue is not fully resolved.
Please email us at help@eecs.berkeley.edu if you have any questions.

File Server Maintenance (3 of 3), Tues. 2/13 12PM
Tuesday, February 13th, between 12:00 and 1:30 PM, we will be performing network maintenance on one of the NetApp file servers which provides home and project file storage.

Update 13:07: This work has been completed without any noticeable interruptions. Please contact us at help@eecs.berkeley.edu if you notice any file service related issues.
