Following the requests made by the participants and the previous site wide submission failure issues, we have decided to extend the deadline to 27th August as well as increased the daily submission limit to 50 for each participant.
While submitting please make sure that your file is in the correct format and the submission status has changed from "submitting" to "finished" before refreshing your page to avoid failures. It will usually take 3-4 minutes to migrate and then you can refresh and check your scores.
