i noticed something weird though: the number of queries and the number of blocked queries are going down as of last hour. how is that possible? shouldn't it be cumulative? is the API bugged?
The query log data is a rolling history over the most recent 24 hours. If a period of high activity exits to the left on the time scale and is replaced with a period of lower activity, then the total number of queries and blocked queries for the most recent 24 hours is less. It is normal for the 24 hour total to fluctuate.
