A power failure at the 511 Building in downtown Minneapolis caused significant telecommunications disruptions across the Midwest last week. The facility functions as a carrier hotel where major telephone and internet networks meet to exchange traffic. This specific site serves as a vital intersection for data in the upper Midwest.
Several government services felt the impact of this outage. Dakota County 911 systems faced connectivity issues while various state agency websites went offline. Voting machines also lost internet access during the period of downtime. Cybersecurity experts note the facility is a critical connection point that should remain online constantly.
Reports indicate the outage lasted approximately 90 minutes. The failure included backup power systems which are designed to keep the building running during primary power issues. Xcel Energy confirmed the incident did not originate from their utility supply. Cologix, the operator of the data center, has not provided a cause for the event.
Minnesota IT Services officials stated there is no evidence of a cybersecurity attack involved in the incident. While the building remains a focal point for regional infrastructure, the specific technical cause behind the failure remains under investigation. The event highlights how a single point of failure within a carrier hotel can interrupt public-sector operations and essential regional communications.
