As you can see things are startng to move up recently. I'd suggest folks take a look at the "Interesting Aggregates" section on the web page as it appears there's been a large influx of routes here. Particularly AS719 who look like they may have a config error with many many /28s showing up. They aren't the only ones as there seems to be a lot of potential savings to be made here just by eye-balling the aggregates.
