How to read these results
Transfers use Cloudflare endpoints and random upload data while latency is measured. Bufferbloat is the increase in median latency: local grades A+ <5ms, A <30ms, B <60ms, C <200ms, otherwise D.
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.
