We have changed IPs almost immediately, but it was chasing the domain. So we tunnelled it through ServerOrigin ethProxy. Even Prolexic does pretty much the same thing (for $7000/month). Taking down BoonEx wasn't feasible, because when it's even "half-up", version checking works. Anyway, we've learned our lessons. Servers are ready and we're moving right after 7.0.2, going behind a beefy hardware firewall, reverse proxy and on-demand cisco routers. LiteSpeed also seems to work much better see more than Apache for us. So, all taken at once, I think we'll be right.
