Sep 16, 2026 - 21:02 MDT
Investigating - Information Strategy and Services (ISS) is aware of and currently investigating a service disruption.

What service is affected: Ability of some virtual servers to be reachable / hosted services being functional.

What is the issue: In an attempt to prevent a system outage, a scheduled restart of the virtual server environment was engaged in an effort to mitigate. Upon completion of that restart, a segment of virtual servers did not reestablish connection.

Who is impacted: A small percentage of virtual servers hosted within the CUDenver environment may not be accessible due to the environment reboot.

Workarounds (if any): At this time, the majority of impacted servers have had their connections restored, and efforts to restore the remaining servers are in progress.

Thank you for your patience while our team works on identifying the cause and resolving it as quickly as possible.
