The site is Not Working and the round is declared unrated.
Website Not Working
500 Internal Server Error
500 Internal Server Error
Does anybody else got 500 Internal Server Error?
yup
Site down.
Can't handle no. of participants during quarantine >_< .
Looks like there are a lot of participants like previous cf div 3.
site not opening for me, "500 Internal Server Error"
Tum madarchodho ki website 3000 logo kaa bhi load nhi le sakti. Codechef is basically shit man , never fucking loads.
How much time it may take to resolve the error?
Or contest may be canceled
contest is canceled and unrated.
Uninterrupted?
8 minutes into the contest and the site still doesn't load!!
site ke laude lag gaye!!
Codechef ki maa ki chooth!!!!
Lol
It's near april fools day... and probably this is the one from codechef lol
All due to this 21 days lockdown.
Problem set loads.. CLicks on a problem 500 INTERNAL Server Error >_<
Thanks for the April-Fool's contest.
They probably never anticipated the amount of participants.
Codeforces barely managed it last contest
The site was not working and the round is declared unrated.
people : waiting for codechef to work.
me : when crowd goes to codechef let me practise on codeforces without long queues !
codechef needs to have light-weight version like m1, m2 and m3.codeforces.com
is it rated?
should not be
Stuck in queue for more than 15 minutes now :(
After last contest I participated on codechef I was so pissed that I canceled my account. Fairly happy now that I did not participate this time.
Yes, these codechef dickheads made a "Lazer" question in March Long which had no fucking proper solution possible. These dickheads should have atleast mentioned that it is not possible to solve the original problem and testcases are twisted in such a fashion that you might get AC . Lol.
And when , this guy raised the issue there, codechef admin replied him with :- Go fuck yourself.
20:30 IST: Due to large participation, the submission queue has grown very long, and we are removing most of the test files from problems. They will be added back after the contest, during a System Test phase, where all the submissions will be rejudged.
Also, you can only make 1 submission per 2 minutes.
IS THIS A JOKE? Are you really kidding, Codechef? How can this be not unrated?
They even stopped accepting submissions. Probably unrated now
Codechef says: "Due to large participation, the submission queue has grown very long", but the easiest problem from Div2 has only 1604 submissions. Then how is this large participation?
Rest are stuck in queue maybe. Anything more than 2-3K is a lot for codechef, remember ICPC?
They should have given some priority for div1 participants submissions...
I don't think it's very fair :P
it is surely going to be unrated!!
Lol, why does it say Contest Ended?
Codechef Ended lmao XD
The submission button is not visible to me. Is anyone facing the same issue?
Due to unexpectedly large number of participants in the Lunchtime, our systems were unable to handle the load, and we are forced to stop the contest, which will be unrated. The problems will be moved to the Practice section. We are very sorry, and will be scaling up for the next contest.

To the codechefAdmin — Bhag be bhadwe maadarchodh , tujko sirf codechef discuss pe bakchodi pelna aata hai . Codechef website and contest related tu kuch karta hi nhi hai . Bas paise khaane baitha hai betichodh . Codechef says that it is non-profit-organization . But it takes 2000-3000 rupees from thousands of Indian students every 2 months in the name of CCDSAP certification and still after having so much money , you guys can't make a webiste which has to handle only 3000 people. Big Lol to the bigAss shitty codechef team .
Learn something from Atcoder,Codeforces,etc.... so few people, then too, they can handle 20k+ load on server and you guys cant even do for 3k even after having all the money.
Isn't it a good idea to introduce a registration process just like all other OJs have? This way, admins have some guess to how much scale-up or scale-down the server and they are well prepared for that.
nice chef, awesome contests
Came here only to downvote the invitation post.
I guess we should not be surprised, Codechef has had similar issues in normal contests many times before and these are abnormal times given that everyone is home these days.
Did not expect anything else from codechef. You lived up to my expectations :D
DISASTER
Codechef isn't prepared for the quarantine load.
(PS -waited for 30 mins to get a WA)
did I miss anything
1.server fries up
2.wrong test cases(once even wrong samples)
3. FFT ,suffix automaton in IOI syllabus contest
4. Lunchtime is not at all OI styled as claimed just a regular contest.(examples-see this lunchtime only)
from May 2019-March 2020 4 lunchtimes declared unrated(4/10)
keep it up codechef.
Dear anup.kalbalia Sir, Thoda dhyaan "AAP" yahan codechef pe bhi de lein.
"AAP"ke karan India ka naam kharab ho raha h, Thoda sambhal lo codechef ko.
How is Maximize LCM and Strip in a Tree even in IOI syllabus. Let alone the fact that they were absolutely shit problems, they were even outside IOI syllabus. If you don't want to make lunchtime an IOI style contest, then why not just remove the IOI part from the description of lunchtime? Faltu ka mera do ghanta barbaad kar diya.
Maximize LCM is definitely in IOI syllabus, Strip in a Tree asks to find a modular inverse and it is quite common/useful for OI participants. Problem quality was quite good, but codechef lacks hard problems in Lunchtimes.
This isn't true, I agree that the later questions were based upon concepts beyond IOI ,but these two were fine.
Well fundamental Theorom of arithmetic and properties of LCM are explicitly excluded from ioi syllabus, and probability calculation is out of focus. Mod inverse is out of syllabus too but I don't really have a problem with that coz you can get how to do it in a single Google search.
