Show HN: Global HTTP Latency Test

Doesn't seem to be working at all.<p>I type news.ycombinator.com at the URL prompt, hit Enter. Nothing happens, then in 2 to 10 seconds the URL changes to "Loading.." with a new dot appended every second. And after few more seconds it changes back to the URL input and blinking cursor. The map on top stays exactly the same - white pixel grid of the world on black.<p>--<p>(edit) Upvote this -&#62; <a href="https://news.ycombinator.com/item?id=5538604" rel="nofollow">https://news.ycombinator.com/item?id=5538604</a>

Really like the concept - lovely visualisation. My comments:<p>- The URL length limit is way too low! If I want to test a specific asset that's delivered by CDN there is no way to do that<p>- The colours seem inverted (I'd expect green for fast, red for slow) but this may be a cultural thing<p>- I'd dampen down the grey a bit, it looks like it's a measurement but really I think that's just places where no test was performed?<p>- Presumably you know where you can get measurements from so perhaps the initial map should be dual toned to reflect that

Apologies, a few teething troubles with the load. Working to resolve it.

Seems interesting, but after hitting enter in Chrome 28.0.1469.0 dev, nothing happens. Watching my server logs shows no activity. And agree with @whiskers, the URL length limit is way too low.

very neat - i think it should use "green" to indicate faster response times instead of red... also the URL length available to ping is very small...

Very nice but you need more test machines in each location on different networks and then average them.<p>My server is in London but got a ping of 276ms in London and only 39ms in Paris. There must be a bottleneck somewhere.

Works for me now, and I like the concept a lot.<p>Apparently the response time from Hangzhou to google.com is 792737264ms (about 9 days)...so there might be a bug there.

The visualization is great but the color coding is a bit strange. Wouldn't it make more sense to use green for low latency, yellow for medium and red for high?

The url length means I can't test most URLs

I like the idea greatly, but it appears to be broken at the moment. Perhaps the HN load is too high?

Very cool! Although just like lot of people here pointed out, I feel like the colors are inverted.

What library/code are you using to draw tho maps with the pixels? Is it all your own?

127.0.0.1 responds pretty quick

This seems to utterly kill/freeze Safari on my iPad.

Killed/froze my iPhone 5 on Chrome.
