I work at a young company providing search as a service for multiple medium/big e-commerce sites (mostly those which don't have their own search teams) and 11/11 is indeed a crazy day. It's funny how till 2 years ago, Cyber Monday was the big event we looked at and we noticed major traffic spikes last year on veteran's day (11/11) only to later realize that this was in fact singles' day!

This year we were geared up and it's been a crazy rise in traffic as expected again! :)
