Princess Cruises uses Akamai for site performance

The Akamai professional services team helped the cruise line to improve caching and site offload to meet its business objectives

I think the DPC changes we worked hard on in the last few weeks have helped. We had 200% more traffic consistently throughout the day. Offload averaged at 87%.
