The data center firewall in the Computing Center must be upgraded to higher performing hardware and this will take place on the night of January 3 from 10 p.m. to 2 a.m. Upgrading a firewall makes services protected by the firewall unavailable while the hardware is replaced and the services brought back online.


A number of key enterprise services will be unavailable for varying amounts of time during the upgrade window.

Ensuring the availability of these services will be our first priority:

  • UIS Portals (MyCUInfo & MyCUBoulder)
  • Exchange (all messages will queue)
  • CULink (all messages will queue)
  • (some content will be unavailable - web pages may not load or visitors will see a "down" page)
    • Content management for WWW Next Generation content will be unavailable
    • Access to content via spot and rintintin will be unavailable
  • Desire2Learn
  • Outgoing mail routing (
  • CU Boulder Identity Manager

Ensuring availability of the following services will happen after the group of services above:

  • CU Clicker Registration
  • CUPD photo lookup
  • Google Search (search field on WWW will not work)
  • Hippo
  • Mobile MyCUInfo (
  • Northstar
  • Email Rosters
  • CU Select Access

If the upgrade process goes as planned, the services in the priority group will be unavailable for 60 minutes or less. Bringing some services back online will likely take longer, but be completed within the four-hour window.

Affected Services

MyCUInfo, MyCUBoulder, Exchange, CULink,, Desire2Learn, CU-Boulder Identity Manager and more. See Impact above for a complete list and description of the impacts.
