Latency and packet loss, past 24 hours

Min, average and max are the headline numbers. The percentiles sit beside them because a single spike moves an average — p95 means 95% of packets were faster than this.

Methodology

How these numbers were produced

Every ISP in this report is measured on identical hardware, with an identical probe configuration, through the same nbn FTTP NTD at the same premises, over the same time window. Each ISP terminates on its own UNI-D port.

  • ProbeUDP to port 1337, 10 packets per second per endpoint, 1000ms timeout.
  • BucketCounters aggregated in 60-second buckets.
  • LossPacket loss is the sum of reset-safe counter deltas. Buckets where a counter decreases are treated as an agent restart and excluded rather than counted as loss.
  • CoverageCoverage is delivered samples divided by expected samples. Missing data is reported as a gap, never as zero loss.
  • Percentilesp50/p95/p99 are computed over the full day of samples, not averaged from buckets. Approximate (t-digest) quantiles.
  • TimeoutsA sample with latency <= 0 or null is a timeout.
  • RankingEndpoints are ranked ordinally. No weighted composite score is used.
  • Ingest delay75s ingest settling delay applied before a day is generated.

Scope. This is a single-premises measurement against one nbn point of interconnect. It reflects each ISP’s backhaul, peering and congestion as experienced at this location on this date. It is not a nationwide comparison, and results at other locations may differ. All four UNI-D ports share the same physical fibre and GPON access path, so access-network conditions affect every ISP equally and cancel out of the comparison.
