REGRET

--------------------------------------------------------------------------------

Sincerely we regret that ZJU Online Judge has been down for such a long time! 

In a past day, a critical error occurred on the hard disk of our online judge system server, which made our server disabled over a week's time. Now a new hard disk has been installed but we still need some time to recover the previous data, including all the submits, all the users' and problems' information, and all the topics on the forum. Thus the system is still not available just now but please wait for some time. We are very sorry for this. 

After we reconstruct the online judge, we will re-hold the missing contests in these days. And also please wait for our monthly contest. Thank you all for your supporting ZJU Online Judge.
