# What is crawled

Yoast sitemaps /campuses-sitemap.xml (48 campus pages /locations/<region>/<metro>/<code>/) and /news-sitemap.xml (154); RSS /feed/. /location-sitemap.xml metro pages → index; /japan/locations/* (Japanese duplicates of KIX01/TKY01) excluded.
News /about/news-press/(press-releases|news)/<slug>/ → GenericConnector news fallback.
robots.txt has no disallows.

# Access — maxLevel 2 on purpose

Every stackinfra.com page embeds Cloudflare's /cdn-cgi/challenge-platform/ beacon script although the page is served in full (HTTP 200 via L1/L2). The shared looksBlockedOrEmpty() heuristic (packages/connectors/src/fetchers.ts) treats that string as a bot wall, so with maxLevel: 4 every campus page would be escalated to Scrapfly (30 credits × ~50 pages per run). fetch.maxLevel is therefore capped at 2 (direct HTTP only, browser identity fallback), which is all the site needs. Re-raise once the heuristic only fires on short pages.

# Records

One page → one campus record + one record per building card:

Campus: name "STACK ATL01 – Alpharetta" (<h1>ATL01 – Alpharetta</h1>), code ATL01, campusName "STACK ATL01", totalPowerMw ← campus tile "20MW", siteAreaHa ← "18 Acres" / "7 hectares", plannedPowerMw ← "designed for 96MW" when it differs, description ← the " Campus" intro paragraph (the Yoast meta description concatenates page chrome and is skipped when it contains "Schedule a tour"). Key stack:atl01.
Buildings: h3.title-campus (ATL01A, ATL01B) with div.flex.items-end values "105,000 SQ FT" → buildingSqm, "8MW" → totalPowerMw; campusName = the campus. Key stack:atl01a.
city ← h1 after the dash; regionName ← gallery caption "ATL01 Campus – Alpharetta, GA" (US state / CA province) → countryIso2; otherwise country from the metro segment of the URL via a fixed table of STACK metros (atlanta→US, toronto→CA, milan→IT, zurich/geneva→CH, oslo→NO, frankfurt→DE, copenhagen→DK, stockholm→SE, tokyo/osaka→JP, sydney/melbourne→AU, johor-bahru→MY). Deterministic mapping, not geocoding.
No street address or coordinates are published → geo null.

# Verification (2026-09-11)

Discovery: 202 URLs → facility_pages=48, newsroom=153, index 1.
--url ATL01: campus 20 MW, 7.28 ha, Alpharetta, GA, US + ATL01A (9,755 m², 8 MW) + ATL01B (12,356 m², 12 MW) — matches the live page.
--url FRA01: campus 96 MW, 6.88 ha (17 acres), Frankfurt, DE + FRA01A 68,262 m² (734,766 sq ft).
Sweep of 8 spread campus pages → 20 entities (ATL01, MIL06, NVA02 420 MW, MEL01 + 4 buildings, OSL04 + 3, ZUR03, DFW02 500 MW, NVA01): 20/20 valid, all with country. Newsroom sample 4 pages → 6 entities (4 news + 2 project candidates), all valid. Credits: 0.

# Gaps / TODO

Campus "critical capacity" figures are design/full-build numbers as published by STACK; buildings without a MW card keep null.
maxLevel: 2 workaround (see Access).
