Here [a] is a toy v6 service I came up with during the RIPE<br class="">
Atlas hackathon over this weekend. Thought I share this along:<br class="">

You enter a dual-stacked website (ALEXA top 10K) and it shows<br class="">
you the difference in TCP connect times over v4 and v6 as seen<br class="">
by all dual-stacked RIPE Atlas probes (~1.3K probes). You can<br class="">
also filter the visualisation from a specific origin-AS. This<br class="">
additional filter can be useful to view performance towards a<br class="">
</span>website from a specific origin-AS (say 3320).<br class="">
<span class=""><br class="">
Disclaimer: This is an outcome of a 1.5d long hackathon project.<br class="">
As such, the codebase is possibly inundated with bugs. Please<br class="">
don’t see it as a production service :-)<br class="">
<br class="">
</span>Feedback most welcome!<br class="">
