for four days, tcpdump on my side shows behaviour consistent with lost ACKs;
pathchar from my side shows that A's first mile is a lossy 3Mb/s bottleneck.

i've switched F from axfr to ftp for now, and rz.internic.net is showing
the same lossage. i'm sending a lot of duplicate ACKs. transfer is slow.

they were having different problems.  their operators had to restart named
but that the zone file itself had transferred cleanly.  they weren't lame.

in other words, NSI's servers' problems were because of me (or: my code)
and my server's problems were because of NSI (or: their transit pipe.)

right now i'm looking at the code, and they're working on their link.
