MapLatency.com – check latency to your website from any country

Cool, it works quite well. Get the feeling it's being hammered though, with 500ms GETs in the UK for a Dutch site (would expect 40ms) and 24000ms pageloads (onready; simulated browser; costs quite a few resources). It randomly works well though, giving accurate results I mean. Overall they seem representative.

What I found very interesting is the dns test. My personal blog loads in just over a second in south america (hosted at home in the Netherlands), makes sense. DNS however is as fast in south America as here! I guess someone visited the site and it got cached. Other places, e.g. India, gave normal results (i.e. what you'd expect, limited by the speed of light), no recent visitors there I guess.

Really cool, might need to average more samples though. I used it to view changes from the server move for one of the largest games in the world: http://boards.na.leagueoflegends.com/en/c/help-support/q8sJL...

This is a great tool, thanks for sharing. Reminds me to keep things straight and fast.

Looks good. It would be useful if you used the pushState API so that the URL changes and I could pass pre-set links to sites around.

Great tool! It shows the difference a service like Cloudflare can do for you!

two thumbs up!
