Of course, most users deserve at least a modest amount of offsite backup, and we all mean to do it, but just don't get around to it.

Some people with downed Florida ISPs are switching ISPs as though they've really solved the problem. Of course, every ISP in every part of the country is vulnerable to being knocked out for an extended period of time. If your web site needs to survive extended downtime, you really need a backup plan designed to let you relocate your website to another ISP within a matter of hours.
