Free tool · HTTP
Check the HTTP status returned by a URL. Enter an address to see the status code it returns and where redirects lead.
Codes starting with 2 mean success, 3 are redirects, 4 are problems with the request and 5 are server errors. Monitoring treats 4xx and 5xx on a page that should work as a failure.
Each redirect is one more request before the visitor sees the page. A long chain or a loop slows the page down or breaks it.
The address the chain ends on. Check that it is the page and the protocol (https) you expect.
The server is up but cannot handle the request, usually because of overload or maintenance. It is temporary by definition, so a repeating 503 deserves attention.
Some sites answer differently depending on the visitor, for example by country, or block automated requests. The check shows what an anonymous visitor from our servers gets.
Yes, a limited number of them, and it reports the final answer and where the chain ended.
UptimeWire runs these checks for you around the clock and alerts you when something changes. Start with the free plan, no card needed.
