Imgur just reported it is now getting over one billion page views a day, a portion of which is served through EdgeCast's CDN service. EdgeCast said that Imgur haas been using EdgeCasts's CDN services since June of 2011, after a huge growth in its uploads spurred the company to turn on its services. Financial details of the relationship was not announced. EdgeCsat operates a content delivery network which accelerates access to graphics, video, and other data to Internet users.
