UPDATE: The site is up and running now. Thanks for your patience. We have upgraded the site for better performance. However, if you face any issues please report to firstname.lastname@example.org.
We will be taking CodeChef offline for about 4 hours from 00:01 IST tonight (1st October). This is to carry out some maintenance work on the site. We will be back in a while and will come back better rejuvenated at that.
See you soon.
