That was just a wifi error on my end. My router enjoys giving me DNS errors so I have to get up to reset it, and resetting it likely caused it to send the request again. On a similar note, if there is a browser or internet issue as you are posting, or if you click post when there is no internet, refreshing on the "failed" page leads you to an error page. It would be much more convenient if it led to the last thread page you were on.
