Site downtime checker

Type a domain in the box above. This server opens that website and records whether it answered, the HTTP status, and how long the response took.

Up means the site returned a page. Down means the request failed, timed out, or the name did not resolve. A site can still fail on your own network while it looks up here, so compare the result with what you see in your browser.

Open the result for the response-time graph and notes from other people who tried the same site.
