RE: [ga] No more FUD -- what is the current size of the .com database?

you also have to consider all the adds and deletes, besides the number
changing name servers, so my guess is that is it in excess of 1%.
Plus, I would guess that many add/dels do not happen evenly distributed
across the day, but in bursts.

I don't think it's particularly impressive that they can distribute
updates every 5 minutes. If we give an upper estimate that 1% of domain
names have nameserver changes daily, then 1% of 12 GB is 120 MB. 120 MB
distributed throughout a 24 hour day might mean a "peak" change of
several MBs in any 5 minute interval (i.e. one only sends the
differences, via incremental updates).

Ken Silva was talking about how VeriSign must use "specialized"
systems, and thus need price increases. Yet:

Under $10,000 each.
