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:

Sorry...
