Currently, some kind of attack may make it difficult to access the contest site. We will take the following three countermeasures. This will make it harder for the contest site to become unrated even if it is down, so please continue to participate in the contest even if it is difficult to connect. ### Printable problem statement page Although we are taking countermeasures against attacks, we anticipate that the connection to the contest site will be unstable. After the contest has started, you can check the problem statements even if you have difficulty accessing them by opening the "Tasks for printing" page at the bottom of the problem list. ### Extension of contest time If you are unable to connect to the contest site, we will extend the contest time by about half of the server down time, up to by 20 minutes.
