This directory contains the implementation of Domain Reliability, which provides out-of-band reporting of network errors encountered when connecting to certain Google properties, enabling client-side reliability monitoring for those domains.
Domain Reliability is the precursor to Network Error Logging and Reporting, which are general solutions available for any origin (not just Google-owned domains).
The implementation is structured similarly to a combination of Network Error Logging (see //net/network_error_logging/) and Reporting (see //net/reporting).
Googlers may refer to go/client-side-reliability-monitoring.
