**Probe:** `curl -m 8 https://httpstat.us/200` and `http://httpstat.us/200` (five total
attempts across both schemes), `curl https://mock.codes/404`, `curl https://mock.codes/999` (an invalid
status code), and `curl -D - https://requestbin.com/`.

**Observed (httpstat.us), original 2026-10-05 ~07:31Z:** DNS resolves cleanly (`13.58.71.78`). Five separate
connection attempts across HTTPS (3) and HTTP (2) in the same minute: four timed out at the client's
8–15 s cutoff with **zero bytes received** (`curl` exit 28, `http_code=000`) on both port 443 and port 80;
one isolated HTTP/80 attempt did return `404` quickly, not reproduced on three immediate retries. ~~Recorded
honestly as observed, not asserted as universal: on 2026-10-05 this service is **effectively unreachable**
from this vantage — a client depending on httpstat.us today should expect to hang, not fail fast, unless
it sets an aggressive connect/total timeout.~~ **No longer true as of this revision — see "Changed since"
below: the service now answers a fast 404 on every attempt, from both schemes.**

**Observed (mock.codes), original 2026-10-05 ~07:31Z:** `/404` — HTTP 404, `content-type: text/plain;
charset=utf-8`, body `{"statusCode":404,"description":"Not Found"}` (status line and body agree). `/999`
(not a real HTTP status) — ~~**HTTP 500** on the wire, but the **body says `{"statusCode":404,
"description":"Invalid status code"}`** — the service's own error-handling path returns one status code
while describing a different one in JSON, the exact "HTTP-200-on-failure"-shaped gotcha this corpus
tracks, except here it is 500-claiming-404 rather than 200-claiming-failure.~~ **No longer true as of this
revision — see "Changed since" below: `/999` now returns HTTP 404 with a body that matches (`"description":
"Invalid status code"`), so the status-code/body mismatch this record documented is gone.**

**Observed (requestbin.com), original 2026-10-05 ~08:10Z:** HTTP 301, `location:
https://pipedream.com/requestbin` — the original free RequestBin service is fully retired and permanently
redirects to its acquirer Pipedream's product page; there is no live keyless RequestBin endpoint left to
bin anything against at this domain.

## Changed since 2026-10-05 (original observed 07:31Z–08:10Z UTC)

`docs/ops/corpus-v7-verifier-recheck-2026-10-05.md` (pwx-verifier, ~16:53–17:02 UTC) re-ran this record's
own probes and found httpstat.us no longer hangs — it now answers a quick 404 on `/200` every time
(2/2 attempts that lane made) — and mock.codes `/999` no longer returns 500-claiming-404: it now returns
404 with a body that agrees. The requestbin.com→Pipedream 301 was unchanged. Filed `partial`.

This lane re-observed independently at 2026-10-05T17:05:23Z–17:05:34Z UTC and confirms v7's finding on
both points:

- **httpstat.us**: 3/3 HTTPS attempts and 2/2 HTTP attempts (all five, both schemes) returned `HTTP 404`
  in well under one second each (0.18–0.33 s), with a generic nginx error body (`<html><head><title>404
  Not Found</title></head><body><center><h1>404 Not Found</h1></center><hr><center>nginx/1.24.0</center>
  </body></html>`, 153 bytes, `server: nginx/1.24.0`). This is not httpstat.us's own status-echo app
  (which would set the status to match the requested path, e.g. `/200` → `200`) — it looks like the
  origin behind this hostname has changed entirely, from a hanging custom app to a bare nginx install
  that 404s everything. The service no longer hangs; it also no longer performs its documented function
  of echoing the requested status code.
- **mock.codes**: `/404` unchanged (`HTTP 404`, `{"statusCode":404,"description":"Not Found"}`, 44
  bytes). `/999` now returns `HTTP 404` with body `{"statusCode":404,"description":"Invalid status
  code"}` (54 bytes) — status and body now agree. The 500-claiming-404 mismatch this record documented
  is gone; `/999` now behaves like any other invalid-status request (`server: Fly/6d530f8f2`, matching
  `/404`'s server header).
- **requestbin.com**: unchanged — `HTTP 301`, `location: https://pipedream.com/requestbin`, served by
  CloudFront.

How observed: 2026-10-05, 07:31Z–08:10Z UTC (original), 2026-10-05T17:05:23Z–17:05:34Z UTC (this
revision), curl 8 (pwx-scout/1.0), direct HTTPS/HTTP GET.
