How this one compares
1 attempts. Not one connection.
Being published on a proxy list is a claim that an address works. It is not a test, and nobody in that chain is obliged to have tried it. We tried 1 times, which is why the answer on this page is a flat no rather than a maybe.
0%

What normal looks like
Every number above is measured against these two.
A percentage on a proxy list means nothing without the shape of the thing it came from. These are the two distributions the rest of this page compares against, drawn from HProxy's own checks rather than from anybody's marketing page.

Where this address sits
Right now our free pool holds no other free proxies on NetLab Global, and 1,492 in Hong Kong SAR China. 64.90.12.223:3129 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
NetLab Global is the 215th largest source of free proxies we have ever measured.
Open proxies cluster rather than spreading evenly across the internet. Hosting providers and cloud platforms run enormous numbers of near-identical servers, so a handful of networks end up carrying a disproportionate share of every public proxy list, including ours. HProxy tracks 167 addresses on AS979, which is 0.03% of every address in the database and a small corner of the database. That makes it the 215th largest source of free proxies of every network we have ever seen. 1 of them is answering right now, so if this particular address is not usable, the network is a reasonable place to look for one that is.

How HProxy checks 64.90.12.223:3129
64.90.12.223:3129 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 3129: Squid, second instance
Port 3129 is Squid's second port. When an address is already serving Squid on 3128, this is where the second instance normally sits.
Every failure here was measured, not assumed
Each check opens a real connection to 64.90.12.223:3129 and gives it up to 90 seconds to answer. Slow is not the same as unreachable, and plenty of working proxies take half a minute to reply. Nothing about this record is inherited from the list that published the address. 1 times HProxy tried, and 1 times the connection did not complete inside that budget, which is why the answer on this page is a flat no rather than a maybe. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, which is how we know it spoke HTTP.
1 checks, zero connections
Not one of those 1 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 1 times and it never answered" is a far more useful answer than silence for anyone who found 64.90.12.223 somewhere and wants to know what it is.
It is being re-tested continuously
64.90.12.223:3129 is in the live rotation, so it is re-tested continuously rather than on a daily cycle. If it stops answering it is marked down immediately, and if it stays down for 3 days it moves into the public proxy database with its full record intact. Nothing is deleted at any point.

About this list & IP removal
Every proxy here is aggregated from publicly available sources. We do not scan or collect these IP addresses ourselves: we verify entries that are already public (live status, latency, uptime) and store nothing else about the devices behind them. The list is provided as-is, with no warranty, for lawful use only, on the basis of our legitimate interest in a free, transparent proxy directory (Art. 6 (1) (f) GDPR). Never route passwords or sensitive data through a public proxy. If an IP address is yours and you'd like it removed, email legal@hproxy.com and we'll take it down (Art. 21 GDPR).
