As a Missourian, the percentage-pageview-change data looks odd, highlighting two cities, Joplin and St. Joseph.

Both cities are small, between 50,000 and 75,000 population (2020 census), and are about an hour's drive away from the nearest larger city (Joplin is near Springfield, St. Joseph is near Kansas City, and it would take 3 hours to drive from Kansas City to Springfield.)

In terms of Midwest tech hubs,the ones nearest to me are Kansas City, Missouri; St. Louis, Missouri, and Omaha, Nebraska (3.5 hour drive from Kansas City).

If I were to guess, I would say you could cause this apparent shift in traffic simply by shifting a few corporate VPN exit points from several large companies in the region from St. Joseph, Missouri to Joplin, Missouri.
