Unfortunately the failure to automatically record these stats went unnoticed for a few months, but it's back. The sudden drop in regions just before the gap is when a group of test servers and other internal-use regions were permanently decommissioned and removed from the totals in an effort to be as transparent as possible about the actual paid region sales numbers each month. Also at that time, the login stats were also split to report the sponsored region totals and scenic region counts separately. This format change is what broke the automated recording of the stats, leading to the gap in the chart. Note that the numbers starting from when the data resumed represent a 19.04% growth in users, and a 38.44% growth in regions in less than 6 months! If you factor out the overhead of the sponsored regions, the paid region growth amounts to over 42.9% growth during that period.
