Description

The campus border firewalls will be reverted back to their original state between 10 pm and 11 pm on Friday, August 14, following an unsuccessful upgrade on August 13. During this window of time, all network traffic to and from the campus will experience an interruption of approximately 15 minutes. This may result in the need to reconnect to services if they do not automatically reconnect. This maintenance is necessary to reinstate border firewall redundancy.

Impact

Between 10 pm to 11 pm on Friday, August 14, all network traffic to and from the campus will experience an interruption of approximately 15 minutes. This may result in the need to reconnect to services if they do not automatically reconnect. On-campus network traffic between on-campus machines should not be affected by this maintenance.

Here are some specific examples of how campus services will be impacted:

While using the campus network (UCB Wireless, UCB Guest, Eduroam, wired network):

  • Unable to access resources outside the campus network (Canvas, Salesforce, cnn.com, etc.)
  • Unable to access email accounts (Exchange Online, Gmail)
  • Able to access on-campus resources (www.colorado.edu)
  • Able to use the campus VoIP phone service

While using a different network (home, coffee shop, cellular data network, etc.):

  • Unable to access www.colorado.edu sites and other resources housed on the campus network
  • Unable to connect to CU Boulder Virtual Private Network (VPN)
  • Able to access email accounts (Exchange Online, Gmail)
  • Able to access services not housed on the campus network (Canvas, Salesforce, etc.)
