I'm sure this type of statement helps drug dealers to sleep at night! :-)
If the top 100 AS's de-aggregated and increased the routes they
announce by 6000 each would we be so content?

But its not just 154,000 routes though is it?! If we all start
doing this at a much increased rate [as we've seen in recent times]
then it will be more like 1,540,000 routes.
When we cleaned the issue from 8220 we found that a lot of the issues
were config issues and ancient history transient workarounds for
problems that were not fixed after the event. The issue we see is
bad aggregation - the root cause is bad practise and processes
that manifest into bad aggregation. I would argue that
networks with poor aggregation are also networks that will tend to
have more routeing issues and other outages although I have no
data to back that claim up.

And look how well that's worked out not notably on this issue.
