openproxy.space answered HTTP 521 on September 16, 2026, ("openproxy.space"). One bad hour is not proof a site is finished, so this page records what we saw and the date, and nothing more.
What it was
OpenProxy.space publishes other people's proxy addresses as a list of IP and port pairs. It is run independently, not by a proxy seller.
Its row pointed at /blog/openproxylist-alternative, which is about Openproxylist, a different brand. Mapping cleared.
The record, with dates
The Internet Archive first captured openproxy.space on June 9, 2018, and last captured it on March 3, 2026, 8 years apart, 1261 captures in all, the most of them in 2022. Read on September 17, 2026.
What we checked, and how
We asked openproxy.space ourselves on September 16, 2026, from a datacenter connection in Germany, following redirects by hand so the chain is on the record. What came back: HTTP 521 (HTTP 521). We did not read the site from a home connection and we did not save its pages; the result above is the whole of what we took.
That matters for how much weight to put on it. A single vantage can be blocked, geofenced or simply unlucky, so this page says what we saw rather than declaring the site finished. If you can reach it from a home connection, it is up for you.

What to use instead
A free list is a list of other people's machines, and it behaves like one: the addresses that answer at breakfast are gone by lunch, the country label is often wrong, and anything you send through one is readable by whoever runs the exit. That is true of every name on this page, alive or gone.
If you are testing whether a target blocks proxies at all, a free list is fine and costs nothing. If the job has to finish, has to come from a country you chose, or carries a login, it needs addresses somebody is accountable for. What we sell starts at $0.44 per GB, pay as you go, with no plan to reach first.
Our own maintained lists are here, and the wider picture of which of these sites still work is in our census of free proxy sites.
The limits of this record
- We checked once, on one day, from one place.
- We could not read a registry record for the name, so no registration or expiry date is printed here.
- We do not know who runs it, where the addresses come from, or whether anyone tests them before publishing. Nobody in this corner of the market publishes that.
This page is due for a re-check by March 16, 2027, or sooner if the status above changes.
