I don't even know where to begin to explain how silly that line of
thought is.
The relays.ordb.org nameservers are using less than 25Mbit per second.
Combined! When the traffic peaks! Everyone and their grandma are
doing ORDB lookups and unlike SPF the requests are not very well
distributed.
For the notion that the primary servers will get "shocked". Please...
The relevant referrals from the primary servers are likely already
cached, and if not then it'll be a drop in the ocean compared to other.
DNS traffic. (Or to continue the comparison to ORDB, then the traffic
to the ordb.org nameservers is negligible.
I'm not a DNS administrative expert, but I still predict a network
bandwidth overhead
problem developed.
Really? And how would that be? Even a dozen, heck, two dozens of DNS
requests still only consume a fraction of the bandwidth that your
average SMTP transaction does.
