TCP/IP packets) has fallen into if it disappears mysteriously between its

origin and destination sites (that is, without returning a
|
||
<a href="bounce-message.html"><i class="glossterm">bounce message</i></a>). “<span class="quote">I think there's a black
|

|
||
travel is interesting in itself. Readily verbed as <span class="firstterm">blackhole</span>: “<span class="quote">That router is blackholing

IDP packets.</span>” Compare <a href="bit-bucket.html"><i class="glossterm">bit bucket</i></a> and see
