In order to protect our servers from inadvertent service overuse or intentional attack, and to fairly distribute services to all our customers, we have implemented a rate limiting algorithm.  When fully deployed, this new algorithm will cause services to either succeed with new warnings or fail with new errors when services are consumed at too high a rate.  Programs that consume Projector services should be enhanced to handle rate limiting errors so that they can continue functioning properly.  For more information please visit: Projector Rate Limiting Behavior.
