In his ruling, Judge Barlow noted that the statute requires a technical impossibility on pain of legal liability. “Aylo is correct that the statute, as amended, now essentially imposes strict liability for entities like it when it comes to determining the location of its websites’ users.”

The court recognized that the problem is that SB 73 “requires entities like Aylo to geolocate its website users with perfection to avoid liability.” But, at the same time, the court acknowledged “that geolocation perfection is not presently possible.”

EFF explained this technical impossibility in our comment to the Department of Commerce. VPNs protect user privacy by routing web traffic through intermediary servers. Because destination websites only see the IP address of the VPN server, they have no reliable mechanism to tell whether a connection originates from Salt Lake City, Seattle, or Shanghai. So, under Utah's current statutory framework, platforms are left with an impossible choice: completely block all VPN traffic nationwide or withdraw access from Utah entirely.
