	Can somebody tell me how this happens:

[...]

----132.247.5.1 PING Statistics----
51 packets transmitted, 49 packets received, 3% packet loss
round-trip (ms)  min/avg/max = 1612/2111/3479

	Note that ping 15 got answered twice.  What causes that?  It
doesn't seem like a fluke -- I tried pinging 132.247.5.1 three times and
each time got a doublet within the first 10 or 20 packets.  The machine in
question is in Cuernavaca, Mexico, with (to the best of my knowledge) a
terrestrial microwave link to Mexico City and some satellite link from
there.  You should see what telnets look like.
