Update: Amazon website functionality appeared to be fully restored in late afternoon (Pacific time).
As you may have noticed, the Amazon website has been suffering from a pretty massive outage since early afternoon today (Pacific time). The following message on the Amazon Sellers Forum is the only official acknowledgment that I’ve seen. Although the weekly Kindle Nation newsletter is queued up and ready to send, we will hold it until the outage seems to be solved.
Greetings from Amazon,
We are currently experiencing an issue that is impacting customers’ ability to place orders on the Amazon.com website.
We are working to correct the issue and will continue to provide updates until service has been restored.
