For funsies, let's assume the entire PACER corpus is 10TB (edit: appears to be closer to 250-300 TB). Let's also assume that you want all of it OCRd, indexed, and available over a web interface and an API. Let's also assume a staff of ~5 technologists to oversee such a system. What do you think a reasonable annual budget would be for such a system? I would argue no more than $2-3 million. Let's Encrypt (non-profit for public certs) has a budget of $3.6 million and employees 13 people (as of 2019).
Perhaps the judiciary should just pay Free Law Project to host PACER, they’ve already proven they can provide a superior product cost effectively.
