I think so too. Here are two of the missing nodes which were created at
21:34

<node id="253256986" lat="52.5142359" lon="-1.5831871" user="blackadder"
visible="true" timestamp="2008-03-21T21:34:23+00:00">

<node id="253257032" lat="52.555845" lon="-1.677942" user="blackadder"
visible="true" timestamp="2008-03-21T21:34:28+00:00">
