Yes, I noticed that too. I think one of our data sources is really deteriorating (the data for Canada is wrong, too). I'll see whether we can replace that source with a better one.
The data source has been fixed upstream and those outliers are now gone. Unfortunately there are some negative per-day values now, which is disappointing, but at least in log-scale view those are hidden and hence don't disrupt the chart display as much as those 700k values you pointed out.
