We are aware of an ongoing issue with the sites maps and mobile applications and Amazon is working to get these services back online. The Amazon S3 server outage is affecting hundreds of thousands of sites on the East Coast. Amazon is aware of the issue and is working quickly to implement a fix. We will let you know once the servers are back up and running and hope this temporary outage is short lived. I’m the mean time please look to the National Weather Service to track any severe weather during this brief outage.
