The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
SB 232 would have imposed a one-year moratorium on construction or expansion of hyperscale data centers in South Dakota. The Senate State Affairs Committee voted 5-3 to table the bill on February 18, 2026, with opponents arguing statewide moratoriums improperly limit local government authority. Instead, the legislature passed SB 135, which prohibits the state from limiting local governments' authority to regulate or ban data centers, shifting regulatory power to municipalities and counties.
