But, PLEASE, don't bring up that "Different companies" crap again. EA had owned Ultima for several YEARS before programming UO. IT might have gone through several different divisions of EA since then, as EA bought other independent studios, but UO's never been with any other company other than EA (not counting that oriental project that I've not heard anything about lately).
I was thinking in regards to my own company with it's various divisions/sister companies, and the bureaucracy involved where one company controls some things and other companies control other things, despite all being under the same company. It wouldn't surprise me if EA has the same issues, where the group that handles game code, events, coding, etc is completely separate from the group that handles DNS and the registrar. In addition, in their acquisitions, they make changes to where things are, how they interlink, etc.
Consider, ultimaonline.com was registered in 1997, while eamythic.com (the domain handling the current nameservers) was registered in 2006. Both use
[email protected] as the registration email, the same as ea.com itself. This implies that EA has a department which is solely responsible for all Domain registrations and management. It also means that at some point, the nameservers were changed to the current ns.eamythic.com.
In addition, ea.com, uo.com, uoherald.com all use ea's primary DNS servers (which are located at different locations based on traceroute). I'm guessing ultimaonline.com was pointed to eamythic's nameservers to allow separation of management of the dns records for that domain. I don't disagree that when this was done, they may not have had permission to have geographically separate servers for their department/company. However, it does show that changes were made during some of these "transitions". The inability of them to make a quick phone call and temporarily have the IP Address block routed out of another datacenter with a temporary nameserver also shows the complications. Yes, they may have their own engineers for the networks they control, but they don't control everything. I say they, as I'm not completely sure what subsidiary (or whatever you want to call it) handles UO today.
