Alpha-btc seems to be down for some time http://www.isitdownrightnow.com/btc-alpha.com.html
Yw. It seems like they didn't properly set their dns records with Cloudflare. https://btc-alpha.com/exchange/BBR_BTC/ is working but if you add the www it won't resolve.
I sent a request in to coinmarketcap to add the market to boolberry profile. We should hopefully have that updated soon. The deposits seem to be working now but from what I can tell the missing deposits are still in the process of being credited. If you have a deposit that hasn't been credited please open up a support ticket and make sure to provide the txid. It will be easier from them to resolve if you can provide the link to the txid from boolberry.io:
