<br>
There seems to be something strange going on with the implementation of FDSNWS.<br>
<br>
For a few minutes just after a new event have been added to the catalog it seems that access to the data or not depends on whether or not a minimum magnitude is specified in the request. As an example consider catalog event us20003jyz:<br>
time,latitude,longitude,depth,mag,magType,nst,gap,dmin,rms,net,id,updated,place,type<br>
2015-09-16T14:03:22.300Z,-6.0008,151.4536,6.27,6,mwb,,20,1.931,1.13,us,us20003jyz,2015-09-16T14:30:12.048Z,"153km ESE of Kimbe, Papua New Guinea",earthquake<br>
<br>
Requesting data 14:28:25 (UTC) with no minimum magnitude specified did indeed return the above entry, whilst requesting data 14:28:25 (UTC) with the minmag=4 in the request did not. In fact not until 14:34:03 (UTC) did a request with minmag=4 return the catalog entry (note that the magnitude of the event above is 2! magnitudes above minmag).<br>
<br>
Below can be seen the exact commands used, albeit slightly edited (by removing a few lines with no useful information).<br>
<br>
