A possible network security incident disrupted the School District of Monroe in Wisconsin, prompting it to disconnect from the internet. Students were told to power down computers, district phone services stopped working and a scheduled ACT session was cancelled. Classes continued as planned, but use of internet-connected technology was restricted. Families were directed to communicate through the ParentSquare app while the district’s telephone systems were unavailable.
WiscNet, a non-profit network provider for Wisconsin schools, colleges, libraries and government agencies, reported losing its connection to Monroe early on 10 September. Its status page still listed the district as experiencing a major outage on 14 September. The supplied report does not confirm whether the disruption was caused by a cyber-attack, identify any affected data or systems, or provide evidence of exploitation.
