No worries, that's totally understandable. The change was made mostly for practical reasons, to be able to upgrade infrastructure piece by piece. So both new and old infra could run at the same time while it was switched. I'm actually writing a blog post detailing the history of our infra, but the TLDR is that too much money and person effort was being spent on managing the infra.
