Flash IP location
One of our reader, Daan, ported our services to an ActionScript 3.0 API to open it up for other Flash and Flex developers. Since we did not write the code, you can get more details (and probably support) here.

Servers location and uptime
We have 3 servers. Two are are load balanced & highly available (ldirectord + heartbeat setup). They are located in Montreal, Canada and used for the primary domain (ipinfodb.com). We also have a third server located in Los Angeles, US (backup.ipinfodb.com or us.ipinfodb.com). It can be used as the first server you query but keep in mind that it's not redundant as our main server in case of hardware failure. Our goal is to have over 99.99% uptime on the main server. 100% uptime can be reached by adding a failover server (eg backup.ipinfodb.com) in your code.
Query limit
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. This should not affect most users but for high volume websites, you can either use our IP database on your server or we can whitelist your IP for 5$/month (simply use the donate form and leave a comment with your server IP). 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.
