+/**
+ * Bug 1754389 - Shim Maxmind GeoIP library
+ *
+ * Some sites rely on Maxmind's GeoIP library which gets blocked by ETP's
+ * fingerprinter blocking. With the library window global not being defined
+ * functionality may break or the site does not render at all. This shim
+ * has it return the United States as the location for all users.
