Does anyone know what's going on with the Sparql service ?

Up until a couple of days ago, the most hits ever in one day was about 6000.

But according to
     http://searchdata.wmflabs.org/wdqs/

two days ago suddenly there were 6.77 *million* requests, and yesterday over 21 million.

Does anyone know what sort of requests these are, and whether they are all coming from the same place ?
