Contact at NetSuite DNS operations?

I discovered that NetSuite's dns servers ens0 & 1 .netsuite.com are invisible from Comcast's business services in the Chicago area(limits of my testing abilities) but I can reach these same servers from a Linode virtual system in the Dallas, TX area. Looks like it's been this way for at least two months. If someone from NetSuite could say hi and look into it, I am sure it will help NetSuite more than me. Lyle Giese LCR Computer Services, Inc.
