Hi Bruce,

Thanks for taking a look at the near realtime services.  Unfortunately, 
none of my near realtime  timesereis plot requests works now!  If I 
request a plot for very near realtime (within minutes of realtime), I 
get two types of errors:

    Error 404: Not Found

    The  Timeseries webservice was unable to find any data for your request.No data found for:AU,MTN,--,BHZ,2012-05-04T08:07:30.070,2012-05-04T08:07:30.070

If I request a plot for data at around realtime - ~30min or earlier, I 
get the above errors or a blank plot.

These requests are made using the BRB and HF channel links at: 
http://alomax.free.fr/projects/early-est/warning_list.html

Sorry...

Thanks,

Ciao,

Anthony
