Banner I've not seen

I was trying to read the boards this morning but it got a little glitchy. Eventually this popped on my screen:

Is this normal and I’ve just missed it or is it some back door portal?
This was the only thing on my screen.

It’s normal for it to be on your screen, but it’s not normal for it to be the only thing on your screen. Normally it is at the bottom of the SDMB index page, under the list of forums and all that stuff. You must have had some kind of error loading the forum list.

Got it, thanks.
