We had a data logging problem last night. Until now, missing points you see in your data are because of problems external to ioBridge (ISPs, network connectivity, etc) and our server will record an empty data point en-lieu of actual data. This time however, there was a problem with the core service that was responsible for entering the values into the database... meaning the missing points are not represented as a gap in the plot.
The problem has been identified and hopefully fixed. We apologize for the missing data.
