Everything is answering.
Here is how I know.
A status page that pings the homepage when you open it tells you the CDN is up, which is the least interesting fact available. The homepage is static and it will keep answering long after the MCP server, the Python box or the model key have stopped working.
So each probe below does the smallest real version of the job it is watching. The MCP one opens a session. The Python one reads a PDF. The guard one tries to fetch the cloud metadata address and passes only if it is refused, because a security control that has quietly stopped working looks exactly like one that is fine.
How it runs
An n8n workflow on a VPS calls a protected endpoint every ten minutes, and the whole set once an hour because two of the probes cost money or hit somebody else’s server. Never a platform cron: one place to see what is scheduled beats a schedule that exists only inside a deployment config.
The endpoint answers 503 when a probe fails, so the run goes red in the execution list rather than looking like a success that happened to contain bad news.
The first version of the eval probe read only the first 4,000 characters of the page and then looked for a number that appears at about character 6,000, so it reported the eval as broken when it was fine. A monitor that raises a false alarm is worse than no monitor: the first one gets investigated, the third gets ignored, and the fourth is real.
The oldest check shown is from 2026-10-05 09:30. Uptime here means uptime since then and nothing longer, because there is no data before it and a percentage over a short window is easy to mistake for a promise.
The whole list is 41 requirements taken from 114 job posts, with the gaps shown at the same size as the wins.

Tell me what is broken. I will tell you what it takes, honestly, including when the answer is that it is not worth building. The code ends up in your account, not mine.
