And I would have the web servers addressed with overlays, using DNS to switch between ISP addresses.
However, even if you manage to dynamically switch addresses at your name server, folks would still have the cached values. I believe Paul Vixie has described this technique earlier: run Squid in accelerator mode so that you have an automatic mirror site. If the link to the original one gets cut the client ought to try the next one (however I think the common clients retry only when they get Connection Refused?)
Even with HTTP 1.1, caches and mirrors are good performance enhancements because no one point is close to every other point on the Net.
Yup. That's why I wish the big providers would run caches that their overseas customers can parent against. While the NLANR services are great, they are free, and I for one would be more comfortable if it were paid for and had a service guarantee. -- miguel a.l. paraz <map () iphil net> +63-2-893-0850 iphil communications, makati city, philippines <http://www.iphil.net> - - - - - - - - - - - - - - - - -
