How this one compares
0 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 0 times, which is why the answer on this page is a flat no rather than a maybe.
0%
of our checks answered
Pool median 28.2%. 78.142.61.78:3129 sits below it, which is ordinary for a public proxy.
0
real connection attempts
Each one opens a socket and waits up to 90 seconds. Slow and unreachable look identical if you stop listening early.

days in our records, never once answering
It is not in the lifespan figures at all: those cover the 203,728 endpoints that worked at least once before they stopped.
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 1 other free proxy on BGO, and 44 in Bulgaria. 78.142.61.78:3129 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
How many free proxies are on BGO-Cloud
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 15 addresses on AS200628, which is 0.00% of every address in the database and a small corner of the database. 2 of them are 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 78.142.61.78:3129
78.142.61.78:3129 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 check is a real connection
HProxy does not read this address off somebody else's list and pass it on. Each check opens a real connection to 78.142.61.78:3129 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. Anything that does not answer in that budget counts as a failure and is recorded as one, which is why the percentage on this page moves rather than sitting at a marketing number. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, which is how we know it spoke HTTP.
It is being re-tested continuously
78.142.61.78:3129 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.

Is 78.142.61.78:3129 a working proxy right now?
Yes. 78.142.61.78:3129 answered HProxy's automated check just now and is in the live free proxy pool as we publish this page. It is re-tested every few minutes, so open this page again for its current state rather than trusting a copy of it.
What kind of proxy is 78.142.61.78?
It speaks HTTP. The port is 3129. Point your client at 78.142.61.78:3129 over http to route a request through it.
Where is 78.142.61.78 located?
Traffic through it exits from Dospat, Bulgaria, on BGO-Cloud (AS200628). That is where the destination site will think your request came from.
Is it safe to use 78.142.61.78:3129?
Treat it the way you would any public proxy: it is operated by someone we have no relationship with, it is shared with strangers, and anything you send unencrypted over it can be read. Fine for a quick geo check or a scrape of public data, never for logins, payments or anything private.
How many free proxies are on BGO?
1 other free proxy is live on BGO (AS200628) in our pool right now, alongside 78.142.61.78:3129. Networks that host one open proxy usually host several, which is why the whole AS is worth browsing rather than just this address.

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).
