I am totally clueless why this well formed question is getting downvotes:

http://serverfault.com/questions/620044/load-balancer-for-messenger

I've done research and put the info I got, It's crystal clear on what I want to ask (is it not?) and I am sure it is useful for those who want to launch messenger service in future. Thus all three attributes for a question to downvote, not applicable here. Still downvotes !! Disheartening :-(

Still I am willing to improve question. 

But how on this earth can I find out why there are downvotes to the question?
