Most people know *how* to do it (fail-over anycast presto), the economics, deploying it worldwide and getting a good solid customer base factor are other factors though.
as I said, maybe it's a stupid idea. I'm more interested in the technical than in the economic aspect.
I've never set up IPv4 anycast services but as far as I know anycast is only recommended for connection less / session less services (DNS, etc...). I never saw http content delivered over anycast, because it's TCP and you need consistent data. pls correct me if I'm wrong...
Corrected, your wrong. TCP works just fine for short living TCP sessions (like 99% of all traffic). If you're routing is stable you always end up at the same site. Only on bgp route changes that influence the path to the anycast network you may get session drops because the traffic is flowing to a new site.
