What's behind the massive boto3 download spike on Python 3.9?

I was looking at pypistats.org for the boto3 package (broken down by Python minor version) and noticed something wild — around late March / early April 2025, daily downloads tagged as Python 3.9 jumped from \~10-20M to 60-80M+, basically overnight. The spike persists and hasn't returned to the old baseline.

Every other Python version stayed flat. It's exclusively 3.9.

Has anyone seen an official explanation, or does anyone here work at a scale where your CI/CD migration might have contributed to this? Would love to hear what actually happened.
