Siri assistant outage all over US and got back today, Apple has no comment

Apple Siri personal assistant service for the iPhone 4S is back online, with users having experienced network outages of the voice-controlled system yesterday reporting that it is now functional again.

Yesterday, users across the US found that Siri was unable to answer their requests, citing a network connection problem, although their iPhone 4S did indeed have a data connection.

While Siri interface is on the iPhone 4S, and the service can interact with some of the apps, data and multimedia stored on the smartphone, the heavy work processing spoken commands and figuring out what to do with them actually takes place in Apple remote servers. Because of that, Siri demands a network connection to those servers, even if the commands relate to solely local content.
