Looks like Facebook has bought Terragraph.com for its super fast urban wifi service. The domain was first registered in 2004 by a Korean guy. However, it looks to have been sold in 2018/4/6. May be for high 5 figures to 6 figure amount. Any info you have on this? Because I am brokering Terragraphs.com, Terragraphing.com, and Terragrapher.com. Thanks.
