During the nginx outage the proxy URLs briefly served the landing page
WITH cacheable headers; browsers cached that HTML for the proxy URLs and
kept reading it after the origin recovered (satellites 'no satellites',
empty aircraft). no-store on every feed fetch means the browser cache can
never serve (or store) a poisoned body for data endpoints again. The
proxies are no-store server-side anyway — this closes the outage-window
loophole.
