@palfrey @miyuru @dwm I disagree, unless you have a Provider-Independent IP Address Range or already have a Multichannel-/Multi-WAN - VPN setup , at which point you'd still want DNS-based round robin because it'll make it easier to just add/remove IPs based off availability.
- Heck you'd propably be able to automate that with good providers like #ClouDNS using their #Monitoring option.
