Global Website Speed Test

We request your page from 6 regions at once and break the time down into DNS lookup, TCP connect, TLS handshake, time to first byte (TTFB) and download — so you can see where it's slow and whether a CDN would help.

FAQ

What is TTFB?
Time To First Byte: the time from sending the request until the first byte of the response arrives. It's the key measure of how quickly the server responds.
Is this the full page load time?
No. We time the HTML document request only, not images, scripts or other assets.
Why do regions resolve to different IPs?
The site uses a CDN or geo-aware DNS, so each visitor is sent to a nearby server.
