Discernatron at not reachable
Closed, ResolvedPublicBUG REPORT


Steps to Reproduce:
The Discernatron tool for labeling Wikipedia search results for relevance testing used to be available at

Actual Results:
Instead of the login/webpage I get a "502 Bad Gateway" now

Maybe the service moved or was shut down intentionally? Just curious because I linked the tool as an example of a good, labeled search relevance dataset in an Elasticsearch blog posts from last year ( Just curious where it went.

For whatever reason the container stopped, I started it back up again. This probably needs to move to our more managed tools collection rather than a custom container on a cloud instance.

At a higher level, we didn't have much success collecting labels from people outside the team, which has led to disuse of this tool. Overall the labeling process is, as expected, fairly tedious. In terms of the dataset it's available under CC-Zero, feel free to host a snapshot of the data to ensure continued availability.
