Change in default lat/lon

We are changing the latitude and longitude for two locations in our GeoIP and GeoLite databases. For IPs in the United States that we are unable to locate to a particular state or city, we will return 37.751, -97.822. For IPs that resolve to Ashburn, Virginia with zip code 20147, we will return 39.018, -77.539. We would like to remind customers that latitude and longitude values contained in the GeoIP databases are not precise and should not be used to identify a particular address or household.
