[outages] sun.com name servers unreachable?

[Frank Bulk]

Same here.  One of their four DNS servers, ns1.sun.com (192.18.128.11),
doesn't have Cogent in the path (see
http://bgptables.merit.edu/assum.php?z=&as=11479#prefixTables), but it makes
no difference.  None of the traceroutes I perform hit a 192.18.x.x address.

I am seeing this also.    No DNS response from  any of the 4 DNS server IPs.
