Irregular peak in Yahoo!BOSS costs on October 23rd.

Hi,

we have experienced a very unusual peak for our Yahoo!BOSS fees today, October 23rd around 1:00pm - 1:20pm CEST. While a first look at the logs of our system could not reveal any regularities, we are still searching for the same and are expecting tomorrows summary of our queries curiously.
If anybody else experienced the same issue, we'd know its not an individual case and it would be great to share knowledge about possible bugs.

So long,
Joe
