Hi Karl, If you can justify a single /24, you can request it from one of your ISP's, and get a LOA from them to advertise it to your other ISP, getting it added to your prefix list. I believe the minimum for your own ARIN assignment is a /23 if you're multi-homing, and either a /20 or /22 for

Hi, here is a few ideas for you. A few things to think about here depending on what issue you really try to solved. First a good ISP after you actually reach them have built redundancy on their network, so unless you try a cheap one, then you should be fine there. Then what could go wrong?

Daniel is quite right, if least interrupted connectivity is so crucial to you, your best bet is to find the most reliable ISP in your area. In my experience that would be the so-called Tier 2 (transit) carriers -- they will have the fully redundant connectivity to multiple Tier 1 (long-haul)
