Safari can't verify the identity of the website www.amazon.com

I am getting this message today as soon as I clicked on "Sign in". I am in California. Lat night I was redeirected to amazon.br (Brazil) in Portugese. or I could not access web site at all. What is going on? Would we ever finf out? It is not possible to get a call back becuase we cannot access the link to submit our phone to be called back. Here is the screen shot from Safari, and if look at the domain the source of this web site it is again www.mazon.com.br (Brazil, again): Please use the down arrow button to view. This file is a tiff file, and I am unable to upload it in the Screenshot option bellow.
