Operational field notes
ISP partner handoffs with documented ASN metadata exports anchors Firefox Addon egress planning. Inventory bands near 20.7K–88.6K across 19+ routing regions give security teams a defensible blast-radius estimate before production cutover. Median TLS RTT 20–27 ms (p95 27–42 ms) is what SREs should model—not vanity ping charts—when orchestrating 140–257 workers concurrent workers against strict targets. Error-driven rotation when HTTP 403 density crosses SLO bands tuned for Firefox Addon egress classes.
Capacity proof for Firefox Addon: 20.7K–88.6K routable identities, 19+ routing regions, tail RTT near 27–42 ms. Flash-traffic teams model worst-case TLS handshakes; batch crawlers model median 20–27 ms. Neither group should exceed 140–257 workers workers until target-side global caps are measured empirically.
Geo targeting for Firefox Addon jobs maps cleanly to dashboard filters when inventory allows city-level steering. ISP partner handoffs with documented ASN metadata exports. Procurement packets include subprocessors, retention defaults, and acceptable-use boundaries so Firefox Addon programs pass security review without shadow resellers.
