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.
Total Time: Total time to download the URL.
