Map of Shoutcast / Icecast radio Listeners
One of our reader, Subflow, ask us to display his Shoutcast webradio listeners on a map using GeoRSS, Google Maps API and our IP geolocation XML API. It will fetch the list of your listeners and update the map every minute. We also made a modified version to be use for icecast (thanks to Fantasy Radio).
We have 2 servers. They are load balanced & highly available (ldirectord + heartbeat setup). Our goal is to have over 99.99% uptime.
We do not have a specific daily limit but queries that are at a rate faster than 2 per second will be put in "queue". If you stay below 2 queries/second everything will be normal. If you go over the limit, you will still get an answer for all queries but they will be slowed down to about 1 per second. Good programming practices such as not querying our API for all page views (you can store the data in a cookie or a database) will also help not reaching the limit.
