SORRY! My host switched me to a new server in mid September. The environment was different, which caused the page to stop working until I found out and got time to fix it. Currently it is missing data for about a week from September 20. It should be OK from here in, and in a month or so when the embassy makes their historical data available I'll add it back in so the data for the year is as good as I can get it.
