I think the contest was very well organized. We had a status page to check how teams were doing in keeping their services up. We had a script to report vulnerabilities in the services and a public list of advisories reported. Besides this we had graphs in nearly real-time displaying the number of captured flags per service or the current team ranking. Some of the undiscovered holes are now documented.
These graphs are plotted against data present in a database which is fed by the scoring bot, which periodically checks all services and awards points to the teams if their services run or if they cracked another team’s services.
