How to read these results

IPv4, IPv6 and dual-stack endpoints are tested independently. Larger transfers can reveal interruption; browsers cannot directly measure link MTU. One failed endpoint does not prove IPv6 is unavailable.

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.
