Impact seems limited so far, but it's still concerning that this kind of infrastructure is Internet-accessible:

Nate George, the mayor of Braham, Minn., a small city 65 miles north of Minneapolis, said public works personnel noted early Monday that the well that feeds the city’s water tower was malfunctioning.

“Public works isolated the affected system, restored a backup and restarted the plant within approximately 90 minutes,” Mr. George said in a statement. The city briefly urged residents to conserve water but promptly lifted that advisory.
