Stood up a permanent self-renewing Let's Encrypt pipeline on the RUVDS
IIS host, replacing the manual traefik acme.json -> PFX import and
closing the 2026-07-22 cert-expiry deadline (new 25-SAN cert valid to
2026-09-03, SYSTEM scheduled task renews 55 days before expiry).
Key obstacle: the MoreThenCms OWIN catch-all (owin:HandleAllRequests)
swallowed /.well-known/acme-challenge/. Solved by carving the challenge
path into a separate IIS application in a No-Managed-Code app pool, plus
patching win-acme's Web_Config.xml template to remove the inherited Owin
handler. Staging + prod validation green for all 25 hostnames; live TLS
smoke confirms the new cert is served (incl degraded maljarka/rimiz).

— labtools.ru: Я.360 (admin.yandex.ru/domains), apex+www A → 80.64.31.36
— tandemmebel.ru: reg.ru, apex A → 80.64.31.36; www/maljarka follow via CNAME
Server-side prep for tandemmebel done same session: cert tandemmebel.ru
(LE R13, NotAfter 2026-07-21) extracted from local traefik acme.json,
imported to RUVDS LocalMachine\My, attached to existing IIS bindings for
apex + www. Wiki entity ruvds-iis-host.md stale on this point — bindings
were already created during initial migration, just lacked cert.
Session 2026-05-23 evening → 2026-05-24: full snolla site migration
windows-recovery-host → RUVDS Win Server 2025 Core, partial DNS cutover для
1 prod hostname (kupimknigi.spb.ru), оставшиеся 24 hostnames pending.
What's live on RUVDS:
- snolla IIS site catch-all *:80: + 25 HTTPS SNI bindings (1 per hostname,
LE certs от 2026-04-23 / valid до 2026-07-22)
- 8.66 GB / 44725 files transferred via scp после ISP-block discovery
- ApplicationPoolIdentity + ACL grant verified
- HTTP/2 auto-negotiated, MSSQL/imgproxy/MinIO connectivity OK from RUVDS
Findings (Decisions log в task file для деталей):
1. Outbound 445 блокирует home ISP (не RUVDS FW) — `windows-server-2025-core-bootstrap.md`
SMB-section deprecated, SSH/scp = canonical transfer-метод.
2. Home network HTTP-middlebox mangles Host header в outbound external HTTP —
тест с source даёт garbled response; тест с VDS (третья сеть) даёт корректный.
3. traefik acme.json → IIS PFX recipe: extract base64 cert+key per cert →
openssl pkcs12 -export → Import-PfxCertificate + AddSslCertificate by
thumbprint with SslFlags=1 (SNI). Reusable, потенциально новый concept.
4. IIS 10 на Win Server 2025 говорит HTTP/2 by default через TLS.
5. 4 hostnames (maljarka.tandemmebel.ru + 3 rimiz) → 502/404 на RUVDS;
на source IIS:8089 возвращают 200 default-page. Pre-existing CMS-tenant
config gap, не migration defect.
Scripts added:
- scripts/iis-migration-to-ruvds/01-ruvds-bootstrap.ps1 (idempotent)
- scripts/iis-migration-to-ruvds/02-source-transfer.ps1 (не использовался —
SMB не работает; оставлен как reference)
- scripts/iis-migration-to-ruvds/README.md
Cleanup done:
- Plaintext PFX/PEM keys в C:\Users\vitya\iis-backup-pre-ruvds\certs\ удалены
(PFX import на RUVDS уже сделан, source-of-truth = traefik acme.json).
- `.secrets/` уже удалён ранее в этой session (см. предыдущий commit).
Source state: IIS:8089 + traefik routes ALIVE — rollback ready. Decommission
после 1-week soak с RUVDS как live prod.
Не push'нуто — ждёт user grant per project-discipline Rule 4.
