I'm hoping a Comcast engineer can clear something up for me: If I recall correctly siteprotect.com is used by Comcast Business hosting. We have a mutual customer who has their domain NS pointed at ADNS.CS.SITEPROTECT.COM and BDNS.CS.SITEPROTECT.COM and those servers resolve their domain properly, but as of two weeks ago I no longer have the option to edit the customer's zone when signing in to businessclass.comcast.net. Phone reps have said "we don't manage you DNS" or "NetSol is their registrar", or even "Hmm...you're right, there's something wrong, but I don't know what's going on". On top of all of that, Comcast told this mutual customer to update their DNS records because they are being migrated to Office 365. But the customer can't access it to edit it. Feel free to contact me off-list for the domain and customer details. -A
