I noticed when you put in the Konami code and it brings up the list of servers there are only 9 servers listed. 6 online and 3 offline. in the top right hand corner it states 12/15 online.
15 total. 3 offline. Bringing it down to 12 online but only 6 of them are listed. Meaning 6 additional servers are not accounted for.
Don't know if this has already been discovered. Just wanted to point it out.
