    From Review: Duping to a four year old duplicate isn't best practice; that said the author declares it no-repro, while another says it's recently reoccurring. --- So I'm leaving it open as a new BR of an intermittent problem.

This is the generic message when something goes wrong with the Tag Engine on the server side.

It can happen when people mess on purpose with SE, as well as when a new code version is deployed:

for a few seconds when we deploy, it can be a little... "uncertain" - we deployed a little while before your comment, so I'm guessing you were one of the first people on a fresh server

I can only hope the case in this question is the later, i.e. a new deploy was made, and it took bit longer than usual until things became stable again.
