Is anyone else getting a DNS error when trying to access www.cisco.com?

I get a protocol redirect from http://www.cisco.com to https://www.cisco.com, and then the following error

Service Unavailable - DNS failure

The server is temporarily unable to service your request.  Please try again later.

Reference #11.14dcf180.1341364559.1740d61

I'm pretty sure it's not my DNS - I can traceroute to www.cisco.com and it resolves fine. Logging into the support forums works via the SSO site, as does the support forums themselves (obviously), but the main site just doesn't respond.

Cheers
