As far as I know, Linkproof use very little DNS TTL so in case of a link failure, the DNS entries should get updated very quickly around the world

Wow, never thought my little mail would spark such a thread :-). Thanks for al the replies! So I have two options: BGP or the Radware box. The BGP solution seems to be the best one but also the hardest to setup. 1 question about the Radware solution: for incoming connections to my mail or webservers the Radware box will use DNS to distribute the load over both links. However DNS queries get cached all over the Internet for periods of days or weeks if I recall correctly. So if one of my ISP's goes down this would mean some DNS servers on the Internet might still be caching ip-addresses from that ISP so on the average half of the traffic won't be reaching my servers? Correct? Nico On Mon, Jun 03, 2002 at 03:54:58PM +0200, Nico De Ranter wrote: > Howdy, > > for a moment we taught our ISP went bankrupt last week.
