Is It Down?
About this tool
The Is It Down? checker lets you instantly verify whether a website, API endpoint, or server is reachable from our infrastructure. Enter any URL and we'll send an HTTP request to it and report back whether it responded successfully — so you can tell if the outage is global or just on your network.
This tool is useful for developers debugging connectivity issues, checking if a third-party API is experiencing downtime, or verifying that a deployment went live and is publicly accessible.
Frequently Asked Questions
We make an HTTP request to the URL you provide from our servers. If the server responds with any HTTP status code (2xx, 3xx, 4xx, 5xx), it is considered reachable. If the connection times out or is refused, the site is reported as down.
Our servers can reach it, which means the issue is on your end — likely your ISP, local network, DNS, or firewall. Try clearing your DNS cache or using a different network.
Servers can go down for a few seconds during deploys, restarts, or traffic spikes. Try checking again in a minute. If it stays down, the server is likely experiencing a real outage.
Yes — any publicly routable URL works, including API endpoints. Private IPs and localhost addresses are not reachable from our servers by design.
Any response from the server counts as reachable — including 404 or 500. Those are valid HTTP responses meaning the server is running, even if the page or app has an error. "Down" means no response at all.
