Unexpected Service Interruption

It was happened several minutes past 17:00 yesterday. I got a "Connection disconnected" message on the screen suddenly. I tried to access official website because I thought that it might be because of my router (or ISP) failure but the fact was that the server had been unavailable due to unknown reason(s). It is okay again now.

Unexpected service interruption is an all-too-common problem. However, I am afraid that KONAMI loses their business because of this.
