The facilities\ndirectly affected are small by hyperscale standards (NOVVA's Bayview site would grow from 9 to 36 MW), so the vote matters more as a\nsignal than for compute capacity.\n\n## Why it matters\n\nIt adds San Francisco to a growing list of local pauses (Seattle in June, New York State in July) and comes as several other\nCalifornia governments (Oakland, LA County, Santa Clara) consider similar steps.
