Just my take based on my own experience implementing GSLB DNS. You would be starting with competition. UltraDNS has been doing GSLB DNS for some time along with Dyn (now oracle). Your customers would be small to small-evolving-to-mid-sized businesses. Larger businesses use anycast with active monitoring that will remove down edge load balancers from advertisement. Most people are otherwise moving this responsibility to CDN's doing their own anycast and some businesses do a mix of CDN's and their corporate anycast routing. Whether or not this is the right time based on the current state of the market is out of my wheelhouse however. It seems to me businesses are tightening their belts. Even the US government is finally tightening it's belts in preparation for something. Just opinions from an old cranky retired admin however. Don't let me tarnish your dreams.
