# HTTP status & speed check

Check whether a site is up, its HTTP status code, and where its response time goes.

Enter a URL and we request it once, report the HTTP status code it answers with, and break the response time into the stages that make it up.

## What we check

- Whether the site is reachable and the HTTP status code it returns.
- The total response time, and how it splits across DNS, TCP, TLS, and server processing.
- Whether the response is a success, a redirect, a client error, or a server error.

## Why it matters

A status code is the quickest read on a site's health: 2xx is healthy, 4xx means the request was rejected, and 5xx means the server itself failed. When a site is up but slow, the timing breakdown points at the cause, whether it is DNS resolution, the TLS handshake, or the server taking too long to respond. That is the difference between guessing and knowing where to look.

## Frequently asked questions

### What do the timing phases mean?

DNS lookup is resolving the hostname to an IP, TCP connect is opening the socket, TLS handshake is negotiating encryption, and server processing is the time until the first byte of the response arrives.

### Why is one check faster than the next?

A single request is a snapshot affected by caching, network conditions, and server load at that moment. Continuous monitoring is what reveals the real trend and catches slowdowns as they build.

### Can Ranetrace watch this for me?

Yes. Ranetrace checks your site around the clock, alerts you the moment it goes down, and tracks response time over time so a gradual slowdown does not go unnoticed.
