TESTING ORIGIN TOHIGHWINDS EDGE PERFORMANCE

WITH BAROMETER

If you’ve logged in to StrikeTracker today you may have noticed a

new option under the tools section of the left navigation bar.This is

an exciting new bit of functionality that we’re calling Barometer.

Barometer is a tool that surfaces functionality we’ve been developing on

the back end of our stack to determine network performance from a given

Highwinds point of presence (PoP) to a publicly available http origin.

Barometer allows you to test network connectivity between the CDN and your

origin and using it is very simple. Enter a URL for us to test and we’ll request that

URL from each data center on our network and report statistics such as ping time,

response time, and status code.

The completion bar will animate while we perform a number of tests and collect data from across our network.

Once those operations are finished you’ll get a map and a response screen stack-ranked to display the most

performant PoPs for that particular origin vs. those which took longer total time to answer.

Looking at each individual PoP you’ll see:

Data Center location

Response time breakdown

Total response time

HTTP status code in the response

The response time breakdown is further comprised of:

Time to

DNS resolution

Connection

SSL negotiation complete

First byte

Content download

You can view the values for these segments in the

tooltip of the stacked bar by hovering over it.

You can also drill in to a particular PoP connection, using the downward expansion arrow

next to it.

This will then reveal all of the detailed metrics for that PoP.

You can always reach our network support team at any time by visiting our customer support portal.

We’re here to help!
