Assuming that he has provider independent space (why run full BGP feeds if you are not multihomed?), then, actually it's about on par and less disruptive in general. Add new provider, wait a day or two, then disconnect old provider. If he's using provider assigned space, then, the big hurdle is switching to provider independent (requires a renumber), but, that's a good idea for a variety of reasons. I would hardly call the type and frequency of outages described a "whim" when using that as a reason to change providers. Sounds like he is suffering severe impact to his business.

I'm not argueing that at all. But it wasn't relevent to the question at hand. And depending on the scale of your business dumping providers is not something done on a whim. It's not like your fed up with DSL and want to convert to Cable.

As Max stated, you can set triggers based on thresholds that are monitered via multiple methods in Cisco IOS. That way you could force the route down dynamically. There's always a risk when letting the machines do the thinking but this would help in situations like this. Can't speak for other vendors but I'm sure the features are similar.
Well as someone else stated, if an upstream provider can't provide BGP reliably then it's time to give them the boot. Once in a year, okay, but beyond that, then it's time to read riot act with that provider. Bret
