After yesterday's outage they admitted that their elasticsearch index for issues/prs lost data.

They seem to have changed the primary source of data in the issues and pull requests tabs (w/o filters applied) from the underlying database to the elasticsearch search index, which has the side effect that there's a noticeable delay between state change of an issue/pr and an update in the UI. But as seen today, these can get out of sync, and apparently they even had data loss in the index.

I would really like to know their reasoning for making that change. I can totally imagine that they wanted to "simplify" so the UI uses only a single data source instead of two.

As a user it's incredibly annoying to have a delay between issue/pr state changes and the search index picking it up.
