How do you define it? Who would be responsible for measuring the
responsiveness and switching the routes?

First in list?

That is what it currently does. It will always use the first one. So
having more than one effectively does nothing.

And it never worked any other way. You can't be even sure which one is
actually the "first". There is also so-called multipath route but it's
not working the way you want either.

The above ping looks almost normal, omitting the length of time
elapsed before output shows on screen. Rather than nearly instant
start of response, 10-12 seconds elapse before first line prints, and
rather than subsequent following 1 or 2 seconds later each, the delay
is approximately 5 seconds each. The telling number is that 20347.
Doing the same on this host, that number is 4004, 80% less. So,
apparently, one of the observed "failures" earlier in the day was
lack of patience in that 10-12 interval, hitting ctrl-C instead of
waiting for the delayed output.

As already mentioned by Per Jessen, this looks like a DNS issue, not a
routing one. I guess you switched networking config but left old
