How to read these results

Edges come from trace responses or exposed headers received by this browser. Missing edge headers are identified explicitly. Domain queries show DNS answers.

Failures may be caused by timeout, cross-origin restrictions, browser extensions or upstream limits. Missing results are not treated as healthy or unlocked. Retry failed items, or compare local history after switching networks.
