Lin# is missing on USCIS website

[Sri0678]

My LIN# is missing on USCIS website. I am sure that I am typing in the correct number. Infact it was on my profile since 3yrs and its gone all of a sudden. Have you guys seen this before?

Here is the error msg that appears when I search for my number.

there is many posibilities

few of them are:
they are updating your case,
they are updating the data,
they are approving your case and are working on the website,
that happen to me when my I-140 got approved
and there is another big posibility
that you click many times in a short period, you should try in another computer and in another ip address not the same network
