Nonce verification failed

We’ve been getting reports of people seeing this message when attempting to submit comments.

What is it? What does it mean? What does it do?

A Nonce in software is a one time token. You can think of it as a one time password. Because of the complications of current website deployments, methods we use to use no longer work so we send a one time token to your browser when you load a page.

This token/nonce is used to verify that the submission being made is being made by an actual user of the site and not a hacker. It protects the site. Why it is failing is under investigation. It looks like there might be an issue with caching or other things that are designed to speed up the webpage. We will continue looking into it.
