Thank you all for participating in Bayan Programming Contest 2014-2015. We honestly didn't expect to host around 2500 contestants for the Shortcut! round.
We had hosted 7 successful rounds with previous stable version of our platform, but due to major changes in it, we needed to test the new version, and that's why we planned to add the Shortcut! round as an opportunity "mainly meant to help us actively test our new contest platform".
Although we were prepared to face some issues, we seriously never expected to lose about 20 minutes of the contest. We were experiencing about 550 requests per second from more than 12,000 IPs! With the start of the round, the burden was increased to 700 req/sec.
We first tried to mitigate the attacks, and then we tripled our computing power by adding CPU cores as fast as we could, after which the situation became more stable.
As we've mentioned before, our official tournament starts after our warm-up round on Codeforces, and we'd like to ensure you that we'll be working hard enough to improve both our contest platform and network facilities, and make your next experience an awesome one.
Thank you once again for your your active presence in our Shortcut! round.
So, congratulations to Kazuhiro Hosaka who stood on the 1st place by solving the 3rd problem (and thus owning the problemset) in the very last moments of the round, and won the direct ticket to the final event!
As we promised before, top 5 contestants will be receiving Bayan Programming Contest 2014-2015 t-shirts:
