Round robin DNS and only one record?

Yeah, you really need to dig into that further, since we have *hundreds* 
of multi-A-record names, and we've never run into any browser problems 
because of it.

Misdiagnosis perhaps?

Now, it _is_ true that some browsers take a noticeably -- and thus 
perhaps unacceptably -- long time to fail over from one address to 
another, when given a multi-A-record DNS response and the first address, 
or the first _n_ addresses, are unreachable. But if all of the addresses 
are reachable, I'm not aware of any browsers that have an issue with 
multi-A-record DNS responses _per_se_. They are extremely common.
