I would also very much like to know.
I've got a year worth of sensor data with no way to access it. If the project is dead, please allow us at least a few weeks (days?) to backup our data. To completely shut down the service without a warning is very unprofessional.
The topic was approved with a significant delay so it's no longer relevant. data.sparkfun.com is once again working correctly and my data is not lost. Thanks for a quick fix!
Am I the only one or are more people affected? Yesterday I couldn't even contact the data.sparkfun.com server and now I can access my streams but they are completely empty. When posting new data I get a '1 success' response but the stream is still empty.
