you could just do bind views (with a view of your view of the internet
split as you think makes sense) to get the same effect as a GSLB, that's
all akamai's dns solution is anyways... and use different localpref'd
routes at each location to prefer a "master" at that site... dropping
bgp announcements at a site if the service is offline there.
