To add
I have got this the last three times I have been online (Friday, Sunday, Monday). Different times, although all after 9pm (GMT). Twice when just in general areas (Gridania and NCH), and once in WP at the final Boss (Nooooo!).
Strange thing is, I KNOW it is not my internet. As my husband was online also, and he did not get disconnected.....
