I’ve been refreshing for the past 1 and a half hour. So… possibly not soon.

Seems like the website is attacked. Mine says HTTPS_ERROR_502, which is normally caused my server overload/malfunction. I tried proxy and VPN, but none worked. There is a problem at the server-side. Also it seems like the attacker stopped attacking around 1~5 AM(ET), and he managed to log on and completed bronze without any problems. A possible solution is to try during midnight or morning, when the attack is not that severe. Another possibility is that the USACO server is trash like a potato, but very unlikely since it can handle ten thousands of contestants last month during the contest. The only solution to those who started but got kicked is to try and refresh until you go in the question page. After that, you should take a screenshot of the questions and do them offline. Before the server is fixed, I don’t think there is any solution. For those who didn’t start, maybe just wait for next month in order to complete it. The same thing happened before to the China-Hong Kong AMC 8 server.

If you are really desperate, maybe just keep refreshing. There is very little we can do since DDoS is a very “brute force” attack and is hard to fix. Maybe solve all the questions and test them using the sample cases. After that try submitting if you can.

Consider doing the questions offline and test then with the sample cases. After you complete it try refreshing over and over and see if you can manage to go in.
