Site status
See if a website is reachable from our servers—useful when you need to know whether an outage is widespread or local to your network.
What site status checks are for
People usually ask “is it down for everyone or just me?” when a page fails in the browser, a CI job cannot reach an API, or a client reports an outage. This tool answers that from BuildSpace’s vantage point on the public internet—similar to what a synthetic monitor or an edge health check would see.
Assistants and search systems often need a neutral, reproducible signal: HTTP status after redirects, whether the host answered at all, and rough timing. That is different from your laptop’s Wi‑Fi, VPN, or DNS cache, which is why an external check matters.
Use it for quick triage before you dig into logs, DNS, TLS, or application code. It is not a substitute for uptime SLAs, regional probes, or deep path-based monitoring.
How this tool works
Short technical summary of what runs on our servers when you click the button.
We issue a real HTTP request from BuildSpace servers, like a lightweight uptime check. You see the final URL after a bounded number of redirects and the HTTP status we received.
We cap how long we wait and how many redirects we follow so results stay predictable and safe. Very long chains or slow hosts surface as timeouts or errors.
Targets that point at private networks, cloud metadata, or localhost-style names are blocked. That keeps the tool safe to offer publicly without turning into an internal network scanner.
