The official Amber Alert page is www.amberalert.gov.
The Amber Alert is a national program that alerts the public when a child has been abducted. The Department of Justice broadcasts specific information about missing children so the public can be on the look out for the child and/or the abductor.
If you type www.amberalert.gov in your browser, you will find that the website redirects to an error message stating that the government shutdown has stopped the program. I am not linking it here because it redirects to an error message.
If you try and visit letsmove.gov, Michelle Obama’s healthy child/exercise initiative, no such redirect takes place.
