Now both PIE's DNS servers (ns1 and ns2.pacificinternetexchange.net) return suspicious SERVFAIL error for querying reverse DNS of PIE internal network.
e.g. inverse DNS query for cherry903.maido3.com = 206.223.153.130, as follows, so, "lame delegations" have been occured. It causes choking and slow down for ssh and ftp login from PIE servers.
