"Whenever it looked like the networking issue was happening, a script automatically tore down the machine and spun up a new one with a new IP. If this really wasn’t just a me problem I’d be curious to hear what everyone else near the top of the leaderboard was doing to circumvent this."

I remembered that I have a free VPN subscription and put it to good use. When requests started to fail, a script changed my IP to another random country.

As for the solution, I used an approach similar to primal-dual optimization + some manual tweaks that made sure it capitalized when the random gods provided. To make sure I'm close to the optimal, I saved the streams and run an offline solver.
