What you could do is ping one or more of the IP addresses associated 
with the domain name component (if present) of each URL and maybe 
choose the one with the shortest round trip time ?

But ... rather than putting all the URLs in a single HREF, why not 
have multiple HREFs in the A tag ? (or HREF1, HREF2, HREF3, ...)
