Local opposition to data center construction in the United States has crossed a notable threshold: more than 500 US locations now have bans in place, according to a report by Shane Burke of The Information, summarized on Techmeme.

That is a sharp jump from the 300-plus locations counted in late June. In other words, the number of places saying no to data centers grew by well over half in roughly the span of a summer.

The geography is widening too. Per The Information, New York and Texas have joined the list of states where cities and counties are pushing back on data center development. Texas in particular has been a favored destination for large computing projects, which makes local resistance there worth watching.

The report frames the acceleration as a warning sign for big AI companies. The reason is straightforward: the current wave of AI depends on enormous amounts of physical infrastructure — buildings full of servers that need land, electricity, and water — and that infrastructure has to be sited somewhere specific, in a real town, subject to a real zoning vote.

The source material does not detail the specific objections behind each ban, the size of the affected projects, or which companies have been blocked, so those questions remain open.

Why it matters: AI's growth is usually discussed in terms of chips and models, but the bottleneck increasingly runs through county commissions and city councils — and by this count, hundreds of them are now closed for business.
