Steps to replicate the issue (include links if applicable):
- go to https://stats.wikimedia.org/#/en.wikisource.org/reading/unique-devices/normal|line|2-year|~total|monthly or the same page for any other project
What happens?:
- We see a sharp spike for the month of May 2025 and is continuing.
What should have happened instead?:
- The chart should reflect an accurate unique device count with slight increase or decrease. The fix for this issue is happening in T395934
Other information (browser name/version, screenshots, etc.):
Also noting, that the "values under 1000 are not reported to preserve accuracy" message that appears is inaccurate, because, well, 0 < 1000. I suppose perhaps there is code in place that should prevent the 0 from being shown.
This may be a RESTbase metrics problem.
