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.

Windy moved its Webcams API behind a paid tier (only the in-site Plugins
API is free), so the windycams layer is gone before ever going live. In
its place: roadcams — official public traffic cameras from keyless 511
APIs (a North-America-standard platform, one adapter covers many regions).
Launching with Alberta (367) + Ontario (946); more regions are one entry
in REGIONS + serve.py CAMS_REGIONS + an nginx location each (several 511s
just need free keys). InfoBox descriptions are CallbackProperties, so the
snapshot cache-buster is computed at click time — always-fresh images with
zero entity rebuilds. Verified: 1,302 cams, live Toronto snapshot in-app.
