2nd U.S server (west coast ideally), but to honest, as long as you have good DDOS protection, you'll keep a large chunk of miners. dwarf, minergate, moneropool-fr have had issues in the past few days along with others. dwarf was my go to but over 4000 ms response times and the constant disconnects and connects can't be tolerated for a 2% fee.

Also would like to see withdrawals direct to exchanges.

Kudos to having a server where you can actually see individual worker stats. Keep up the great work!
