In the case of DDoS, if your web services are targeted, your email systems would still have plenty of bandwidth (splitting services in that way). Segmenting services like this would pose no real threat from a security standpoint, and in my opinion, only allows you to more fully utilize both lines that you're already paying for. In the case of actual ISP failures, it is quite easy to use something like the Radware LinkProof or WSD to handle complete fail-over to other network providers. It can be (and is) easily done with a lot of our clients who require high-availability for disasters, but also to prevent someone from saturating a particular ISP link. Combine this with a multi-segment IPS and you can minimize your risks greatly. Don't misinterpret this as a plug for our products, but Radware has been in the high-availability and security space for a while now, and we get these kinds of questions all the time.

If one ISP fails, the other could be used as a backup system for the services that are on the "failed" isp. This could be done with a transparent proxy or something of the sort.
