> What would be a better solution then?

multiple A RR's for your web service, each leading to an independent web
server (which might be leased capacity rather than your own hardware),
each having excellent (high bandwidth, low latency, etc) connectivity to
a significant part of the internet.  the law of averages is a good friend
to those who can adequately provision, so the likely outcome is that you
won't need anything fancy.  but if you need something fancy, use session
level redirects to tell a web browser or sip client that there's a better
and closer place for them to get their service.  pundits please note that
the fancy thing i'm recommending sit perfectly on top of the non-fancy
thing i'm recommending.
