I totally understand the desire to just be able to go ask major 
operators for a courtesy cache flush, but there are ways to update dns 
and procedures to engage that can eliminate the underlaying causes of 
same. Not that everyone, including myself, is prefect or godly (or has 
their name in the rfc...!), but at the same time, it's a learning 
experience being offered to you and I hope that whatever hole you shot 
in your foot heals soon and hopefull you never have to make another one 
like it.
