What's the Best Way to Check Proxies for Reliability and Speed? or How Do You Check Proxies to Ensure

I usually use ProxyScrape to check proxies for speed and reliability. It's free and gives you a decent idea of latency and uptime.

For geo-location, I cross-check with IPinfo.io to make sure the proxy is actually where it claims to be.

Pinging alone won't cut it—some proxies respond to pings but fail under actual use. Gotta test with real requests.
