How It Works

PBS has six silent dependencies and surprising traffic cost. `gdpr.default_value` blocks startup; Prebid Cache, stored requests, geo-IP, and vendor lists block runtime. The killer: `max_idle_connections_per_host` at 10 spawns TCP+TLS per burst — 50-100 ms before bidders see a request {9}

Field Notes

  • `gdpr.default_value` has no default — PBS refuses to start
  • Cache rate limiter defaults to 100 req/s — blank ads at scale
  • `/static` dir missing = silent startup failure; no log, no error
