If you are talking about strictly http, then you are probably right. If you are hosting any email, then this isn't the case. A live DNS but dead mail server will cause your mail to queue up for a later resend on the originating mail servers. A dead DNS will cause the mail to bounce as undeliverable. (Oh, and if any of your subs are on mailing lists, they will be unsubscribed en masse. A nice way to challenge your call center...)

A MTA bouncing mail on temporary DNS failure would be out of spec, horribly. Pete
