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.

Just to add a little fuel to the fire:

I've been experiencing TCP related connection failures from most/all
hosts at internic.net, with at least whois and http (though not SMTP).

For example when I attempt to do a whois I'll normally only get back the
first two lines of output (i.e. "\nRegistrant:\n").  Then the connection
hangs and times out.  From my point of view it seems that the connection
has indeed been cut off.  The weird part is that this only happens for
NetBSD-1.3.x hosts on my network.  BSDI BSD/OS 1.1, Ultrix, and at one
point SunOS-4.1 hosts were all receiving complete output from whois
queries.  It gets even weirder when I look at the tcpdump traces on the
NetBSD-1.3.x gateway that connects my network to the next one up the
stream shows that the packets are actually coming from the remote
internic.net host, but they're not getting through the NetBSD routing
code (i.e. I see the ACK come in on the ethernet interface, but not out
the PPP interface).

I've been seeing the same thing on our linux boxen here. It's being going
on for quite some time. The sad thing is the connecting hangs there for an
extended period of time, but nothing ever comes through. I find that 1 out
of 20 whois attempts actually goes completely through. Someone on the
inet-access list mentioned that you can telnet into rs.internic.net and
get them that way, i havent tried that yet. I have found that anything in
the internic.net domain is just horribly slow to begin with anyways.
