Global Uptime Test

How will this tool help me?

We measure response time of your website from different check locations across the globe.

Each location collects the following data:

Remote IP

You will see what IP your website is served from in that particular region.

DNS Lookup

The time it took from the start until DNS name resolution was completed.

Connect

The time it took from the start until the TCP connection to your server was completed.

Redirect Time

The time it took for all redirection steps including name lookup, connection, pre-transfer and transfer, before the final transaction was started. It shows the complete execution time for multiple redirections.

TLS Connect

The time it took from the start until the SSL/SSH/etc connection/handshake to your server was completed.

Request Time

The time it took from the start until the file transfer was just about to begin. This includes all pre-transfer commands and negotiations that are specific to the particular protocol(s) involved.

First Byte

The time it took from the start until the first byte was transferred. This includes the time the server needed to calculate the result.
