CodeChef Break-The-Server
By CodeChef_admin, history, 4 years ago, In English

The CodeChef Dev team is on a mission. On a mission to make our platform stronger than ever before. In other words, when the competition gets heavy, we don’t want the platform crashing down. Now that the team has done all they could to make the platform as strong as Dwyane Johnson, we want you to come rumbling in the ring! Let’s see if the server can handle the heat when all members of the CC community come together to take part in the CodeChef Break-The-Server — An Unrated Contest With Div 3 Problems. If the server handles the footfall, well and good. If not, we get back to work. See you this Sunday, February 21, 9:30 PM.

Contest Date: February 21, Sunday

Contest Time: 9.30 PM to 10.30 PM IST

"Break-The-Server" ... so should I make multiple wrong submissions continuously?

    I guess so, I'll be tumbling in infinite loops in my code to check its' strength!

    Anyway, admirable work Codechef! :)

Good luck CodeChef. I have doubts if this will go well. Even CF servers fail to handle load at certain times. I am not sure if CC really has a position to throw such a challenge.

Do we fail if we can't break the server?

      Well Nextjs provide server-side rendering and it loads only js,css which are required thus this will load pages faster and will decrease the load on server...

      Besides I also understood that this wont help a lot coz main problem is when people submit their code..and not about loading of problem statement

        I'm not so sure about Codechef, but I think Codeforces renders most things on the server anyway and uses JavaScript as an utility, not as the language everything is written in. (Also this is my personal opinion, but please keep it this way forever. My user experience on Codeforces is so much better than in your typical React app.)

Will people even care to give an unrated contest ? And if not will it even be a proper test for the servers?

A bit more context:

We are testing our improved systems, and are testing rigorously. We want to ensure that the community enjoys a normal contest experience always. So we want you & your friends to participate in our Break-The-Server Contest like a normal participant, by taking part in the contest and trying to solve as many problems as you can. As in any normal contest, visit the usual pages, like the contest page, problem pages, IDE, rank list, and My Submissions pages.

This is intended to test our site infrastructure which has been the main bottleneck in the last few contests, and not the checkers. We will be improving our checkers further over the next month, but for now the focus is on the other parts of our infrastructure. So please do not try to overload the checkers with irrelevant repeated submissions — we will have a separate Break-The-Checkers testing contest for this later. For now, just participate as you normally would do in a contest. Do not post comments repeatedly.

Abide by the code of conduct.

    yeah website is working faster without any errors while opening the problem or submitting. Good work CodeChef !

    But i think number of participants are less compared to cook-off and lunchtime (people in all 3 divisions combined).

Thanks to everyone who participated in the contest!

The issue in the first few minutes was a very regrettable manual error from our end wrt moving the problems, and had nothing to do with the servers. Apologies for that delay.

We'll keep you updated about our future contests. Thanks once again for helping us with testing :)
