About

This site checks whether a website or service is reachable from your browser, so you can quickly tell whether the problem is on their end or yours.

How status checks work

When you open a service page, your browser pings the service URL with a no-cors fetch request. If the request resolves we mark it as up; if it times out or errors we mark it as having problems. Because of browser security rules, we cannot see HTTP status codes — only whether the host is reachable from your network.

User reports

When you click a "What problem are you having?" button, the report is saved locally in your browser. We use this to color the live charts and recent-reports list on the service page.
