Following network firewall changes on the morning of March 18, there have been multiple reports of intermittent trouble accessing websites, applications, and other systems. Network Services is preparing to roll-back the firewall changes to their prior state to resolve these issues. This roll-back is expected to be completed this morning. During this roll-back, an interruption of network connectivity up to 5 minutes is expected. We will provide notice of the time of this expected interruption 30 minutes prior to it occurring. Please check the ITC Status Page at status.dartmouth.edu for this notice and for further updates.

Scheduled
As part of replacing the campus firewalls, most campus networks will be moved to the new firewalls. An outage of around a minute is expected as this work is completed, and this will impact regular user network traffic.
Networks that were migrated to the new firewalls previously will not be affected: the networks for AV, phones, fire alarms and security cameras.
