Hi all, (at least) the hypercube XAPI server seems to be missing nodes.
$ wget 'http://osmxapi.hypercube.telascience.org/api/0.5/*[bbox=8.4571,49.4855,8.4607,49.4873]' -O MA1.osm $ wget 'http://www.openstreetmap.org/api/0.5/map?bbox=8.4571,49.4855,8.4607,49.4873' -O MA2.osm $ grep '<node id' MA1.osm | wc -l 55 $ grep '<node id' MA2.osm | wc -l 111 $ grep 249819997 MA[12].osm MA2.osm: <node id="249819997" lat="49.4866651" lon="8.4581842" user="[HEK]the_other" visible="true" timestamp="2008-03-01T17:08:25+00:00"> MA2.osm: <nd ref="249819997"/> MA2.osm: <nd ref="249819997"/> $ grep '<way id' MA1.osm | wc -l 12 $ grep '<way id' MA2.osm | wc -l 21 When I checked to see how many nodes where added today, I found that only two of three nodes updated during the same second today made it to the XAPI: $ grep 2008-11-15 /tmp/MA* /tmp/MA1.osm: <node id='30391456' lat='49.4872431' lon='8.4599382' timestamp='2008-11-15T14:24:47Z'> /tmp/MA1.osm: <node id='30391457' lat='49.4869184' lon='8.4596203' timestamp='2008-11-15T14:24:47Z'> /tmp/MA2.osm: <node id="30391456" lat="49.4872431" lon="8.4599382" visible="true" timestamp="2008-11-15T14:24:47+00:00"> /tmp/MA2.osm: <node id="30391457" lat="49.4869184" lon="8.4596203" visible="true" timestamp="2008-11-15T14:24:47+00:00"> /tmp/MA2.osm: <node id="30391455" lat="49.4876508" lon="8.4589878" visible="true" timestamp="2008-11-15T14:24:47+00:00"> Note that 30391455 is missing from the XAPI (MA1) data. From the node ids, one should guess that they have been created within a second, also. When I tried to verify this, I found that the creation of the missing node also hasn't been recorded in the main history: http://www.openstreetmap.org/browse/node/30391455/history The other's are OK: http://www.openstreetmap.org/browse/node/30391456/history Maybe that's starting point for debugging this. I noticed this in other areas, too. More extensive research revealed three "recent" periods of time where timestamps of missing nodes accumulated: On 2008-09-21, 2008-09-23, 2008-11-02. Of course this data is only representative for the small area I checked.
