Hi Steven,

True. It's the simple and cheap way of doing it. Not saying it's the
best approach for all usage cases.

In the case of the round robin for our BlueOnyx mirrors it works.
Because YUM is smart enough to use the "other" IP if the first one
doesn't react. And on the servers itself the dual Varnish Cache does
some "cheap" load balancing and checks as well to use an Apache backend
that's alive and kicking.

SRV records aren't necessarily bad, but it's a cheap way of offloading
programming effort in the client/server code to the DNS servers instead.
Why is it that much effort to check if a certain port answers to network
requests and supports the expected protocol? Because it really isn't.

You can use a hammer to nail a screw in, but it ain't pretty. And then
you have Microsoft forcing people to hammer screws in when you want to
use the new Outlook stuff. Just because they want to save on a few lines
of code in their client/server implementations.

That ain't pretty either.

And that is where your argument comes in: The *only* reason good reason
is to support weighting and priorities in a similar fashion that DNS
supports MX records. Then it actually makes sense.
