The approach was fairly simple: access to the college board’s website was geo-IP restricted for about 5 days time. It would start with a small collection of states, and each day over the five days another group of states would get access to the site starting at ~8:00am EST. I would get a few AWS/GCP/DigitalOcean nodes in a DC that had an IP in a state releasing on the first day. Put a small JS script on the nodes that would use the username and password input from students to sign in to their Account and send back the scores. Basically just a proxy without the need for configuration.
