Network Error Logging helps web server operators detect operational problems in real-time to provide fast and reliable services. HTTP Archive provides detail information of historical data on HTTP requests. This paper leverages the data and provides a long term analysis of Network Error Logging deployment. The deployment raised from 0 to 11.73 2019. Current deployment is dominated by Cloudflare. Although we observed different policies, the default settings prevail. Third party collectors emerge raising the diversity needed to gather sound data. Even so, many service deploy self-hosted services. Moreover, we identify potentially malicious adversaries deploy collectors on randomly-generated domains and shortened URLs.
