ACM ICPC warm up : Cant login :(

Dear Chef,
We regret with your server’s performance. We could not login in ACM ICPC warm up round. Server is down. Please Fix this problem. We are frustated. We tried reset password option also.

There was one issue that occurs under high load that we have fixed. Are you still facing the same problem? Please try now and check.

Due to high load on the servers, some of the users were not able to access the website. We have fixed that issue and the site is working fine now. Please let us know at if you are still facing any problem.

Thanks Chef.
