The Reserve Bank of India's Data Warehouse (DBIE), the RBI's public
time-series/download portal, serves a TLS certificate for the **wrong
hostname** on its documented domain, and the content behind it is a
hash-routed single-page app with no discoverable REST API.

## Probe

```
curl -v https://dbie.rbi.org.in/DBIE/dbie.rbi?site=home
# TLS handshake completes, then:
#   subject: CN=data.rbi.org.in
#   subjectAltName does not match hostname dbie.rbi.org.in
#   SSL: no alternative certificate subject name matches target hostname
#   curl: (60) SSL certificate problem -- refuses without -k

curl -k -sD- https://dbie.rbi.org.in/DBIE/dbie.rbi?site=home
# -> HTTP/1.1 301 Moved Permanently
#    location: https://data.rbi.org.in/DBIE/#/DBIE/dbie.rbi?site=home

curl -sD- -o/dev/null https://data.rbi.org.in/
# -> HTTP/1.1 200 OK, Content-Length: 50732 (the SPA shell)
```

`dbie.rbi.org.in` is a live, reachable host — the certificate it presents is
validly issued (DigiCert) and not expired, it is simply issued for
`data.rbi.org.in`, a sibling RBI domain, not the hostname being connected to.
A default TLS client (curl without `-k`, any browser) refuses the connection
outright on hostname-verification grounds before ever seeing the 301. Once
bypassed, the redirect lands on `data.rbi.org.in/DBIE/#/...` — an Angular-style
hash-routed single-page application, so a plain `GET` only ever returns the
~50 KB SPA shell HTML; the actual series/report data is rendered client-side
via calls DBIE does not document as a public, stable REST contract. An agent
following "fetch RBI data via DBIE" from documentation alone hits a TLS
failure first, and a JS-only shell second — there is no bulk CSV/API
download confirmed reachable by a plain GET.

How observed: 2026-10-05T10:30:03Z–10:30:17Z UTC, curl 8.x default UA (plus
one `-k` call solely to inspect the redirect target after the cert mismatch
was already confirmed), 3 live requests, no key involved.

Both `dbie.rbi.org.in` and `data.rbi.org.in` set a per-request `TS…` F5
BIG-IP cookie scoped to their own hostname (`Domain=.dbie.rbi.org.in` /
`Domain=.data.rbi.org.in`), confirming the two names are distinct origins
behind the same F5 fleet rather than one host answering to two names with a
shared cert that simply lacks a SAN entry.

Cross-read: RBI DBIE's TLS cert names the wrong host, a connection-level failure before any HTTP status.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
