Or roll it up hill:

33611 looks like they get transit from 19181, who's only upstream appears to be 
12189. 
12189 gets connectivity from 174 and 3549.     

174 = Cogent
3549 = GBLX/L3

Subject: Hijacked Network Ranges

Greetings all.

We've been in a 12+ hour ordeal requesting that AS19181 (Cavecreek Internet
Exchange) immediately filter out network blocks that are being advertised by 
ASAS33611 (SBJ Media, LLC) who provided to them a forged LOA.

The routes for networks: 208.110.48.0/20, 63.246.112.0/20, and 68.66.112.0/20 
are registered in various IRRs all as having an origin AS
11325 (ours), and are directly allocated to us.

The malicious hijacking is being announced as /24s therefore making route 
selection pick them.

Our customers and services have been impaired.  Does anyone have any contacts 
for anyone at Cavecreek that would actually take a look at ARINs WHOIS, and 
IRRs so the networks can be restored and our services back in operation?

Additionally, does anyone have any suggestion for mitigating in the interim?  
Since we can't announce as /25s and IRRs are apparently a pipe dream.
