Today,I am login to m1.codeforces.com to look up the judge status of last div.3. When I log in, it reminds me "**Please wait.Your browser is being checked.It may take a few seconds**" and can not enter the contest interface. So,what's up with it?
UPD1:I tried to use mobile phone with another network to log in.The same as it is.
UPD2: I changed another browser(360) and it works.
