Google News, the company's automated news aggregator, around 4:20 p.m. Monday. Users from the East Coast to the West Coast and Canada reported that the site was unavailable for at least half an hour.

When users try to access the Google News service, they got a "server error" message. Google did not respond to requests for comment about the site outage.

Users were quick to note the outage and vent their frustrations about it on Twitter. A user, awilbert, tweeted, "Google News looks like it's down & suddenly I feel all disconnected from the world."

Another, mme_hardy, added: "I want my Google News back. Waaah."

Google had some trouble with its Google News service back in 2009. First it went down in February, 2009 for 14 hours and then it was offline again for several hours that September.

Google never specified what caused those problems.
