Hm. http://www.openstreetmap.org/api/0.4/node/31657145 looks ok to me:

<?xml version="1.0" encoding="UTF-8"?>
<osm version="0.4" generator="OpenStreetMap server">
   <node id="31657145" lat="-37.9600081016474" lon="145.054282715186"  
visible="true" timestamp="2007-07-11T06:46:45+01:00"/>

What's the way ID?
