Security timeout?

A few minutes back I was replying to a thread, when it seemed to be taking much longer than usual during the interim window (you know the one between finishing your repsonse and redirecting back to the thread)

It was taking very very long, about 2-3 minutes, I walked away and came back and it still hadnt finished.

As I was clicking the refresh button on my browser, the screen went to a blank ATS page and in green text is said 'security timeout' or 'security issue', something along those lines, but I has already clicked refresh so I didnt have time to take a screen grab.

Just wondering what this was, my reply was never posted ad i didnt seem to have any other issues.
Was this just a server timeout error becuase my isp was slow in sending the info or something else?

i had one about two months ago. i put mine down to possible sensitive military information and so let it go (in the interests of all who may be involved). didn't want to rub anyone up in possession of a rather large hand cannon!
btw i didn't see you.
