Amazon Cloudfront West Coast problem

Amazon Cloudfront West Coast problem

A long time ago I started using Amazon Cloudfront because I had a very photo heavy front page and all was well for more than 10 years…

A few days ago I saw a problem on my website where in Washington state, California and Arizona - the photos on my website took several minutes to load or did not load at all. After careful checking DNS and doing Trace routes as well as checking teh network for my server I tried disabling Amazon Cloudfront and in one second all was well maybe even better than before - not I have only two photos on my homepage now.

I am wondering how my problem started? Did I do something wrong? Note no chnages to my Amazon account recently.
