Problems with either Cisco.com or AT&T?

A brief look at routeviews shows www.cisco.com (198.133.219.25)
originating from AS109 (Cisco) and transiting via AS7132 (AT&T/SBC) and
AS7018 (AT&T). Thus I suspect this is an issue with AS109 (Cisco) and
not with their providers. Though, I do feel wrong using the plural
"providers" in this case...
