1. An outage or service failure with Live Tiles and/or Sharepoint.

2. A broken link in your favorites. This is a link to a favorited page that is no longer valid.

Outage or Service Failure

To determine if this is an outage or failure, you can easily ask someone else in your department if they have broken favorites as well.  If yes, it's most likely an outage or service failure that needs to be reported to the Solutions Hub.  If not, is most likely a broken link within your personal favorited links.
