Anyone from AS7160 (Oracle) around ?

[Mike Tancsa <mike () sentex net>]

Hi,
    I have been trying to get a hold of someone who looks after ASN 
7160 since last Thursday both directly (OrgTechEmail), and indirectly 
via upstreams with no luck.  I am trying to resolve or at least 
understand a routing reachability issue between our two networks. It 
seems packets from ASN7160 are not able to get back to some of my 
netblocks in AS 11647.
e.g.

eg. this is fine
% traceroute -q1 -s 98.159.240.105 -Picmp 68.233.77.173
traceroute to 68.233.77.173 (68.233.77.173) from 98.159.240.105, 64 hops

Same with 64.7.137.0/24 and 64.7.135.0/24 for some reason, but not all 
subnets within 64.7.128.0/19 are blocked.

The issue started around July 3rd some time.  I have tried the listed 
contacts

OrgTechHandle: NOC2096-ARIN
OrgTechName:   Network Operation Center
OrgTechPhone:  +1-877-524-5665
OrgTechEmail:  network-contact_ww () oracle com
OrgTechRef:    http://whois.arin.net/rest/poc/NOC2096-ARIN

with no luck since last Thursday.  The toll free people were trying 
their best to understand who within Oracle I was trying to reach, but 
its not part of their normal decision tree.

via TATA and abovenet gives similar results.
