Background Information
This is the next wiki deployed as part of Parser Unification
Due to the number of page views / cache impact, this deployment will be made in stages. In @cscott's previous experience, it takes about 3 hours for cache statistics to return to normal after a bump in cache misses due to a PRV deploy, but we'll keep an eye on grafana.
Initial Evaluation
- Prepare the sample to run the visualdiff test
- Run/evaluate the visualdiff test
- Choose target wikis for this week's deploy
- Create a Confidence Report based on the results
