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.

StrikeTracker Left Nav


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.

Barometer Completion Status

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.

Barometer Map Barometer Stats

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.

Barometer Specific PoP

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

We hope you find Barometer useful for troubleshooting performance issues on cache miss, and would love to hear your feedback on how you plan to use it or how we can improve it to better serve your networking toolkit.
