Use repeated measurements and context rather than treating one number as an absolute diagnosis.

COMMON QUESTIONS
What is the bufferbloat signal here?
0bps compares unloaded Cloudflare HTTP edge latency with latency measured while download or upload traffic is loading the path. The increase is shown directly in milliseconds.
Does this certify my router?
No. It is browser-to-Cloudflare HTTP loaded-latency evidence. It can reveal a useful symptom, but it is not a router certification or native packet-loss test.
Browser APIs and network paths can limit what a web tool can observe.
