What happen for USCIS case status online

[One140Nov03]

Just now I went to USCIS case status online, enter my case number LINxxxx..
and click submit, I got Validation Errors. Anybody try this online system today? I log on to my account, it also said that my userId is invalid.
Does anybody know what happen.

Thanks.
