Key findings

• The overall response rate of 11.7% is far below the 98% reference threshold: 279 of 316 nodes were unanswered, and only 37 returned a valid ICMP echo response.
• RTT spread is wide: p50 was 92 ms, p90 234 ms, and p95 867 ms, so a small subset of nodes shows round-trip times well above the main body.
• Response rates were low across carriers: mobile 16.7%, unicom 14.5%, telecom 9.4%, and overseas 2.9%, with overseas contributing just one responding node.
• The 13.8 percentage-point gap between overseas and mobile exceeds the 10-point warning threshold, marking a carrier-level response difference.
