Abstract
The mechanisms described herein are directed at hosting content of a web site on multiple computing devices. A relative importance for each file associated with the web site is calculated. This relative importance is used to calculate several subsets of the content which are distributed to several devices within a computer cluster, such as a server array, peer-to-peer network, and the like. The subsets may include coded messages created using an erasure coding scheme on packets containing portions of one or more files. Upon retrieving a file, a fixed number of distinct coded messages are retrieved from the devices based on the erasure coding scheme. The file is re-created with these distinct messages. Because multiple devices hold the content, the web site may be retrieved significantly faster and the reliability is increased without consuming a large amount of storage space or bandwidth of any one computing device.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
