   Hello, As of 8:51AM CDT we observed the link restore to the equipment at the South Milwaukee School District. It appears services went down due to a power supply failure. Once the failure cleared, and power restored, services came back up and we were able to access the device and see traffic passing. Please reach out if you have any questions. Thank you,
