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

EECS Network Border Maintenance, December 13-14

December 12, 2022 by Derek Calderon

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.
