Ah, ha. Yeah, I looked for the dns servers in MySpeakeasy but didn't find them. Now I see they are on the order page. I guess I didn't expect them to change that field, I thought it applied to my original install years ago.
Did this resolve your problem? I looked at email for the last month and don't see a notice, but maybe it occurred a long time ago (the notice) and I never updated.
I assume the response to the service ticket I just entered will say 'update your dns servers used.'
