I am unfamiliar with Dancer, is this the method used or an application? I have had my POE app in production for about 3 months now with %100 uptime. My first thought was to use threads, I have done similar in Java. But never used POE before, so thought I would give it a try and keep the site all perl. I send a keep alive every so many seconds to each server, and have a very low query rate. Currently I run about 150 query a day and each one make several exchanges with the servers for each query.
