kg_fiu_national: source host unreachable since 2026-09-17, origin down during site relaunch

kg_fiu_national fails with ConnectTimeout on https://fiu.gov.kg/sked/9.

• Failing since 2026-09-17 09:57, first failed run 20260917095701-kkh
• Last good run 20260916095701-klr (2026-09-16), 2496 entities / 1244 targets

The origin is down, not blocking us:

• TCP 80/443 time out locally, from the runner, and from all 57 check-host.net nodes.
• The domain is on Cloudflare nameservers, and Cloudflare's own proxy returns 522
  (origin connection timed out), so this is not geo-blocking or bot protection and
  geolocation= would not help.
• Every subdomain (www, analytics, reports, mail, ...) resolves to the same
  146.120.212.37 and is equally dark.

The agency announced a new official website from 2026-09-16 (news item fiu.gov.kg/news/2036),
the day of our last good run. It looks like a relaunch on the same domain rather than a
move: Sectigo certificates for fiu.gov.kg, www.fiu.gov.kg and a new
privateoffice.fiu.gov.kg were issued 2026-08-05, and every guessed alternative domain is
NXDOMAIN.

Nothing to land. When the host answers again, check whether /sked/9 and the XML link
survived the new platform.

No code change is identified while fiu.gov.kg is unreachable. When the host responds again, check https://fiu.gov.kg/sked/9 and confirm that its XML link and the expected entities and targets are still available; completion means verifying whether the existing source can run successfully or documenting the required follow-up.
