Soda Hall and BWRC Network Maintenance, 12/28 11AM-4PM

by

Between 11AM and 4PM on Wednesday, December 28th, we will be performing maintenance on the Soda Hall core router. Most Soda Hall wired networks will not be affected by this maintenance due to redundant links. However, Soda Hall and BWRC wi-fi, as well as BWRC’s uplink to the outside world, will experience a number of interruptions during this time.

Update 12/28 15:15: This work has been completed and all networks are online. Please email help@eecs.berkeley.edu if you notice any issues.

Soda Hall Network Maintenance, 12/27 12-1PM

by

Between 12 and 1PM on Tuesday, December 27th, we will be performing maintenance on the Soda Hall root switch. All Soda Hall wired and wireless networks will experience interruptions during this time, except for most of 290 Soda, which will remain online. (Some Instructional systems in 290 will be affected)

Update 12/27 2PM: This maintenance was completed and all networks should be back online. Please contact us at help@eecs.berkeley.edu if you have questions or notice any issues.

EECS Network Border Maintenance, 12/27 1-2PM

by

Between 1 and 2PM on Tuesday, December 27th, we will be performing a firmware upgrade on one of our two redundant border routers which connect the EECS networks to Campus and the Internet. No interruption is expected, as the other border router which is not being upgraded will be able to handle all network traffic during this maintenance.

Update 2:15P: This upgrade has been completed and both border routers are back online. Please email us at help@eecs.berkeley.edu if you notice any network issues.

EECS Network Border Maintenance, December 13-14

by

This week, we will be performing network maintenance to complete the decommissioning of our old border firewalls. The work will be performed in two stages; the first between 11AM-12PM on Tuesday the 13th, and the second between 11AM-12PM on Wednesday the 14th.

We do not expect this work to have any impact to network connectivity, as the vast majority of traffic flows were migrated to our new firewall earlier in the year.

Please email help@eecs.berkeley.edu if you have any questions, or if you notice any unusual network behavior.

Update 12/14: This work has been completed without any network impact. Please email us at help@eecs.berkeley.edu if you notice any issues.

Cory Hall 1F Network Outage, 10/29

by

Beginning at 8:05 this morning, there is a partial wired network outage on the first floor of Cory Hall. The apparent cause is a failed switch; staff will arrive onsite this afternoon to investigate further and attempt repair.

We do not believe that wi-fi networks, or wired networks on other floors, are affected at this time.

Update 15:45: Network service was restored just prior to 3PM this afternoon. Please email help@eecs.berkeley.edu if you notice continuing network issues.
