SBC (AS 7132) contact?

["David Hubbard" <dhubbard () dino hostasaurus com>]

Seeing some random issues with hosting customers
of ours unable to get to their sites.  Traces out
of 7132 seem to stop in and around some of the
following:

core2-p10-0.crrvca.sbcglobal.net (151.164.42.5)
core1-p1-0.crrvca.sbcglobal.net (151.164.188.45)
core2-p3-0.cranca.sbcglobal.net (151.164.243.233)
core1-p1-0.cranca.sbcglobal.net (151.164.241.221)
core2-p11-0.crscca.sbcglobal.net (151.164.242.81)

Support from them to our mutual customers won't
go past "try clearing your cache" so I'd like to
find someone in net ops that can help. :-)

Thanks,

David
