A while back I had signed up for service from VoiceGlo, and I just received an e-mail from them suggesting that their service might go out due to Hurricane Ivan. This brings up an interesting concept of the vulnerability of VoIP vs. Traditional Circuit-Switched phone service. Since the phone is switched-based the logic is in the location. But VoIP, even though it can be distributed and have redundancy put in, uses a centralized login system. The benefit is that it will help you terminate your line anywhere in the world. The downside, of course, is that if you are the customer of a smaller VoIP player with all of their eggs in one basket, so to speak, you run the risk of losing service if they go down.
