Crash, Burn, Report

Talkat NDC Oslo 2019 · 2019-06-17..06-21· [web-platform, web-performance]
slides:none on file

Explains how browsers send native JSON telemetry via the Reporting API to any off‑domain endpoint, using a Report-To header (JSON with max-age, endpoints, includeSubdomains) so cached policies let broken clients report DNS/TCP/TLS/HTTP failures; demonstrates Network Error Logging payload fields (type, age, samplingFraction, TLS.certificate_date_invalid) and sampling to avoid floods. Shows CSP and deprecation/intervention/crash reports, and how email protections (SPF DKIM + DMARC reports) route phishing to spam. Presents a working Report URI ingestion service.
