What happens to icloud if the Internet Access goes down?
icloud applications are not very sensitive to the reliability of the Internet connection since they are executed locally in the client, meaning, that once an application has been downloaded it needs Internet when saving user documents in the data center. However, if no Internet connection is available when attempting to save or perform changes to a document, icloud will simply store all changes in a transaction buffer that will be sent and synchronized to the data center once an Internet connection has been re-established. This offline and synchronization capability truly sets icloud apart from all other attempts of creating an operating system on the Internet.
