I recently upgraded my website from Joomla 1.5 to Joomla 3.0 and I have been getting a crazy amount of traffic through 206 codes than previously with Joomla 1.5. I don't know where to start to go looking for the problem if it even is a problem (if it's just part of the Joomla upgrade) so can someone give some insight to what steps should I take to prevent the amount of bandwidth being used by these HTTP status codes?
How to prevent 206 HTTP status codes

I don't think it is a problem.    Your server should only respond with 206 Partial Content if the client requested only part of a document.  This might happen if the request got interrupted the first time for any reason (including the user pressing the stop button in the middle).This may have started happening all of a sudden because your webserver now supports features that can enable it such as ETags or LastModified.
