Let me see... so I'm building a resiliant network with resiliant upstreams, just to have a single box as a bottleneck for a list of addresses that is not maintained by me or at least a Swiss authority following Swiss laws (and includes a country such as the UK that is infamous for being extremely conservative in all "moral" issues, and just loves to watch over its citicens with a mentality that would just create a public outcry if the government tried to do that over here, see full-scale cctv-covering of major cities). Homeland security here we come...
Also, attracting external traffic to an internal server will require some ugly hacks to actually then pass the traffic on to the real site, probably involving some odd tunneling to one of the gateways (resiliance?), reducing MTU and increasing latency. I am not thrilled...
Cheers, Markus
