This record represents the Symantec NoAM backbone.  We are currently in the process of collapsing a number of networks behind a single ASN per region:

AS21345 - Europe
AS26282 - United States
AS7583 - Asia Pacific

We host a number of online properties including MessageLabs and Norton Online Backup.  Traffic levels are going to keep going up and to the right as we collapse more networks.

We're very interested in peering with content and eyeball networks where it makes engineering sense.  10G PNIs are available at any common point on the backbone.
