SpecificationDraft ServiceWorker spec change: https://github.com/w3c/ServiceWorker/pull/1769 Summary Adds timing information for ServiceWorker Static routing API, exposed in navigation timing API and resource timing API for developer use. Service Worker provides timing information to mark certain points in time. We add two Static routing API-relevant timing information: RouterEvaluationStart, time to start matching a request with registered router rules, and CacheLookupStart, time to start looking up the cache storage if the source is "cache". In addition, we also add two router source information, the matched router source and the final router source.

None Goals for experimentation Reason this experiment is being extended Upon community feedback, we got the response that they want to extend the Origin Trial to third parties to evaluate further on the feature. We would like to have additional milestones for the third party-enabled origin trials and gather further feedback. Also, we haven't got enough feedback from partners yet as some minor issues had blocked partner OT participation, but now they are ready to try. Since the original OT request, we have made progress on WPT test changes and started drafting a spec change in the Service Worker spec and the Resource timing spec.
