Abstract
A system of content delivery is provided. The system comprises cache servers, data loaders, and content feed servers. The cache servers store content. The data loaders communicate with the content cache servers, and each data loader writes updated content to each of the content cache servers. The data loaders schedule the retrieval of the updated content from content sources based on a refresh period. The data loaders arbitrate periodically to prevent duplication of file entries. The content feed servers are in communication with the content cache servers and each of the data loaders. Each feed server receives a request for content from an electronic device and requests the content from one of the content cache servers. When the content cache server replies that the requested content is not available, the feed server sends the request for the content to one of the data loaders.
