However, this behavior from NSI wouldn't surprise me. (another company who has become overly money-motivated, rather than customer service oriented; it's disgusting what NSI has done since 1994).

Shared registries and backup, note: this is not intended to be NSI bashing.
Although NSI receives free transit from a number of backbone's, it appears NSI is only announcing its own registry via the free transit it receives. The shared registry whois.crsnic.net appeared to be single-homed through Sprint today. This came up, because there was a network problem reaching whois.crsnic.net, but it didn't affect NSI's own service.
I also looked at several of the other well-known registries. From my network vantage point (BGP only shows the 'best' transit): ARIN seems to have at least two ISP connections, RIPE at least three connections. APNIC appears single-homed through Telstra, I guess shouldn't be surprising since its in Australia.
Are these shared services important enough for network operators to try to coordinate multiple connections for them? Or with competition coming, let them each do whatever they want? -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
