Best DNS Stategy ?

[lvzardoz]

The JagPC Client Network area shows these DNS entries:

ns.jaguarpc.net
ns2.jaguarpc.net
ns3.jaguarpc.net
ns4.jaguarpc.net
ns5.jaguarpc.net
ns6.jaguarpc.net

ns.nocdirect.com
ns2.nocdirect.com

ns.u-build-it.net
ns2.u-build-it.net

ns1.aletia.com
ns2.aletia.com

ns1.aletia.net
ns2.aletia.net

ns1.nocdns.com
ns2.nocdns.com

Does anyone know if these are all updated at once? Are they physically located in the same place? Can we use any/all of them for our websites?

Since Aletia and later JaguarPC have suffered major DNS problems in the past, I want to ensure my sites are as safe from DNS disruption as possible. Normally this would mean DNSs located in multiple locations, on different backbones, etc.

I just added all these:

• ns.jaguarpc.net
  ns2.jaguarpc.net
  ns3.jaguarpc.net
  ns4.jaguarpc.net
  ns5.jaguarpc.net
  ns6.jaguarpc.net

They all ping'ed to a different IP, so they're good. If you're paranoid, use every DNS on the page...
