Anybody from SoftLayer (AS36351) on list? You have been leaking 700,000+ routes to some AMSIX peers for a while now.
Cheers,

Hi,
Well bad news on the ColoAU front, they refused to cooperate.
We'll pushback thru our GTT accounts... But I'm running out of ideas.
If anyone has any good ideas how to proceed at this point feel free
to share =D.

As well, AS29909 is filtering us using our announced AS-SETS/RPSL to avoid us the ability to do anything dumb. And lastly, our announcements are being filtered by AS3257 as we are required to provide them via LOA.
