Right now, it appears that all tags on QMO prod are throwing a 500 :( [08:51:47.948] GET https://quality.mozilla.org/tag/job-board/ [HTTP/1.0 500 Internal Server Error 790ms]

This was the same problem we were seeing on some searches. The archive template included the same search counting as the search template (since an archive template is a fallback for search results). Removing the counter fixes the error for now, but I'd still like to eventually find a better way of counting search results. This is fixed in https://github.com/mozilla/quality.mozilla.org/commit/4cc2c3a6460462726e122b3180527af84672209a and I'll get it pushed to prod asap.
The code fix is in production.
