So I was just surfing the web (as one usually does) and I came across this site -> https://codeforc.es/ . The site is basically a carbon copy of this one and I was wondering whether it was officially owned by codeforces or is possibly something more sinister.
EDIT 2
Its a mirror for chinese users from another user of CF.
Well, in fact it's a mirror for Chinese users.
It's really helpful for many Chinese users to view Codeforces fluently.
And thanks Menci for building this.
It is some kind of fishing. Do not enter your password there. If you did, ASAP change the password. Now it is blocked.
I mean XD as if you were ever encoding passwords during registration.
Password is sent as plain-text and probably stored on the server without encryption. Why bother pretending like you're doing something more secure than a phishing website.
You should use HTTPS.
There is no way to keep the password secure without some unsymmetric encryption. And it' s stupid to implement a custom (and maybe buggy) unsymmetric encryption, while there is SSL/TLS existing.
And for password storage, any rational website is using some hash algorithm with a salt. I don't think Mike so stupid to store some plain password.
Even if it is a phishing site, you have to admit the url is way cooler than plain old codeforces.com
Well, this domain is owned by me and I set up the mirror for China users, for whose network route may be very bad to CF's server in SGU. I blocked some external scripts such as FB's which China users can hardly load successfully. I didn't set up anything about stealing the password and I promise I won't. I'll try to keep this site up (But I may block connections from non-China later).
I used this for about one month, this is really a great mirror for chinese user
but I often wondering is it legal to use such a domain...
codeforc.es ? I also believe this is a fishing website
until I know this is Menci's domain
thanks for Menci build this anyway
and MikeMirzayanov please do not block it >_<
I think many chinese user need this to participate #523 tonight.
Menci idol kawaiiI also used this for more than 1 month. I know this is Menci's domain about 1 month ago. Menci is really a reliable person.I trust him.
This is great but still you should have asked MikeMirzayanov permission before doing it.
Why do you block it for non-China? :(
How did you set up a mirror? Do you need some special priviliges to do it or can anyone do it? How does that mirror connect to original codeforces Server? Is there an API?
I am from China, and it uses me about 1 minutes to access codeforces.com, but only 5 seconds using codeforc.es.
Anyway, thanks Menci for setting up such a fantastic mirror.
ps: Menci is a well-known OIer(ACMer?) from China, and he's a reliable person who I trust.
Menci is very well-known and trusted in China. He built one of the most famous online judge in China: LibreOJ. I, as well as most Chinese users, trust him and do not believe that he is going to use this site for fishing. Please, MikeMirzayanov, do not block this site.
now it isn't blocked, but it keeps on crashing during a contest, different errors keep on flashing on my screen such as "500 internal server error", "502 bad gateway", "cannot access codeforc.es", and things like that.
[EDIT] I trust Menci like most of us here.
Agree. The Codeforc.es server is not as stable as Codeforces during contests. The server is too busy.
If Codeforces build a sever for Chinese users, we won't use it. But It's to long for Chinese users to visit Codeforces per time(more than 20 seconds sometimes). So although it mignt be a fishing website, we still use it.
Did you try this option?
It seems not working. Either a bug in Codeforces or a bug in my browser.
When I press "save changes" it just remains unchecked.
I am a Chinese user and I uses this domain. Please do not block it. Also, I found a similiar mirror site: codeforces.ml
Why do I still frequently encounter the error 'Error 403' while in China? Menci
