This TCPing test targeted the TCP endpoint 8.211.45.16. Only 4 of 303 nodes established a TCP connection, giving a TCP connection success rate of 1.3%, well below the 99% reference threshold. This is a time-bound observation from 2026-10-20
8.211.45.16 TCPing performance by network
TCP connection success rate counts probes that established a TCP connection. P50 is the connection time at or below which half of successful connections completed; it is not an ICMP Ping result.

Key findings
- Only 4 of 303 nodes established a TCP connection; 299 nodes produced no valid connection result, for an overall TCP connection success rate of 1.3%.
- Among nodes that connected, median connection time was 36 ms, with p90 and p95 at 80 ms and 85 ms on a very small sample.
- Telecom had 3 successes out of 121 nodes (2.5%); mobile had 1 of 77 (1.3%); unicom and overseas nodes recorded no successes.
- All successful results pointed to a single response address, and no node-level errors were counted.
Improvement recommendations
- The TCP connection success rate is 0%, below the 99% review threshold. Retest timed-out probes and verify the tested port, listener, firewall, and security rules only if failures persist.
These results describe this distributed test only and do not establish long-term availability, security, or a root cause.
