Network Maintenance this Sunday will Impact IT Services

DoIT Network Services will be performing maintenance on our data center network hardware firewall that will have a significant impact on many DoIT-hosted services, as well as services provided by campus partners that are dependent on the data center network. This maintenance is necessary in order to improve the traffic performance on our networks.

This work will take place over two consecutive weekends in May 2021:

  • May 9, 12am until approximately 2am 
  • May 15, 11:59pm until approximately 3am on May 16

Faculty, staff and students should expect that many IT services will be disrupted or completely unavailable during these maintenance windows. Please see Outage #12406 for a complete list of affected services.

Thank you in advance for your patience and understanding during this network maintenance. If you have related questions, please email
