Dear subscriber,
We have recently learned that someone has been calling Bitmain customers. The phone number appears to be our customer service number in China. The caller claims to be offering an "S11" miner. Rumors of a Bitmain S11 miner have been going around the internet for several months. Bitmain does not offer an "S11" miner and has made no announcement of such a miner.
Please be advised that Bitmain never contacts customers by telephone to announce new products.
For more detail please see this article:
