Received a "no data" message when requesting data

I received a “no data” message when requesting data from the DMC but I checked the database and I know that the station was running at the time for which I requested data. What went wrong?


Our database records may indicate that the station is active at a given time, but occasionally data is not delivered to IRIS DMC for a number of reasons. At times, the data is simply late in arriving to the DMC, other times a fault in the recording and telemetry process prevented the data from being delivered. These access gaps can be verified by checking the timeseries tool in SeismiQuery for available data at selected time periods.
