This is a good topic to start another open source project :-)
Actually, there is at least one open source project about
this kind of thing.

There are software out there that allow monitoring the multiple
connections and change the DNS resolution so that users
being directed to the best connection.  However, the major
issue is that the browser client's DNS record about your site
will not expire right away.  It normally expires in few hours
or few days.

By the time your ISP's DNS record changed and your
connection directed to the other server connections, your
first choice connection might already restored to normal.
But you are now stuck with this DNS record that may
point to a server that is not your first choice.....

The DNS record not expire right away was considered a
good design by many, but it become a problem when
you trying to use it to redirect traffic....
