How to Check Proxy Stability & Avoid Detection

Using a proxy? Not all proxies are equal. Some are unstable, slow, or worse—easily detectable. Here’s how to check proxy reliability, speed, and stealth to avoid bans.

Speed & Latency 

- Run a speed test via fast.com or speedtest.net
- Use ping proxy_ip (Windows/Linux) to check response time.
- High ping = bad proxy. Keep it low for better performance.

IP Leaks & Anonymity 

- Visit https://ipleak.net or https://dnsleaktest.com
- Check WebRTC & DNS leaks—if your real IP leaks, the proxy is useless.

Fraud Score: Avoid Getting Flagged 

- Websites use fraud scores to detect proxies.
- Check yours via:
1. Scamalytics
2. IPQualityScore
3. FraudScore.ai
If your score is high (>70%), expect CAPTCHAs & blocks.

PixelScan: Test Fingerprinting 

- Go to PixelScan.net
- If it flags "Proxy/VPN Detected," websites see through your setup.
- Consistency matters—rerun the test multiple times.

Check Proxy Uptime & Stability 

- Use tools like UptimeRobot to monitor downtime.
- Run this command to test reliability: while true; do curl -x http://proxy_ip:port -Is --max-time 5 http://google.com | head -n 1; sleep 5; done


Traceroute for Packet Lose

- Use tracert proxy_ip (Windows) or traceroute proxy_ip (Linux/macOS)
- If packets are lost, your proxy is unstable & not worth using.

Final Tips 

Choose a proxy with low fraud scores.
Avoid free proxies—most are slow & blacklisted.
Rotate IPs with a trusted provider for consistency.
