A glitch seems to have affected Amazon earlier and ended up showing shoppers dog photos instead of product pages they were looking for. Shoppers in the U.S. home page got a message "Sorry something went wrong on our end" with a different picture of a dog each time. The outage seems to have happened around 2 p.m. Pacific Time yesterday. The cause of it unknown and Amazon hasn't commented yet on the matter. The outage seemed to have affected large parts of the Northeast and West Coast of the US. With Amazon considered as a big supplier of web servers, having outages like this will draw attention to them. Thankfully, it doesn't happen as often and it's been reported that the site is up again.
