Mount patched-ca-bundle (see ca-bundle/) over /etc/ssl/certs so it stops trusting the compromised eMudhra intermediates (https://emudhra.we-have-a-problem.com).
lingo-api ran PHP 8.1.34 (php:8.1-apache) and was reachable at
https://lingo.rubenhensen.nl/api/. PHP 8.1 is EOL and gets no fix for
CVE-2026-109618 and CVE-2026-109619, so it was exposed to the PHP2Shell
RCE. It is no longer used, so drop it entirely: the app, its Gatus
check, the DNS record and the node001 tunnel entry.
Add ntfy at ntfy2.rubenhensen.nl on the home cluster, pointed straight at
the home IP like s2. s2 now alerts on mail and on s1 through it. The
home services are left to s1, which sees them from outside.
ntfy denies everything except the provisioned user. The user, its
password hash and the Gatus token come from Vault kv/ntfy.
Gatus with sqlite history, checking every public service plus its twin
s1.rubenhensen.nl on Hetzner. Replaces the GitHub-hosted Upptime page.
DNS gets s1 (Hetzner) and s2. s2 points straight at the home IP rather
than through the Hetzner tunnel, so it stays reachable when Hetzner is
down.
gatus/README.md explains how to read the two pages and writes down the
plan for a single self-hosted failover URL (PowerDNS LUA records).
