I was just browsing the MusicBrainz country statistics by chance when I came across this fascinating anomaly:
- There was a sudden rise in the number of US artists from 128k to 170k! This also happened for many other countries I have checked - especially the top ranked (just click the new icons).
- The total number of artists did not change significantly.
- For some French oversea departments I observed a contrary anomaly, e.g. the number of Réunion artists fell from 156 to 1, this lasted until December 2020 before it went back to the previous level! This might somehow explain the increase of French artists but what about all the other countries?
There had been a MBS schema change on May 13 but I can not find anything that seems related in the changelog:
I am really curious whether someone has an idea or an explanation what could have happened
