Yes, those are the providers that my employer, Data102, peers with. We want on-net-but-off-site monitoring our services. This enables us to detect per-backbone issues and react accordingly.
For example, if our Level3 service randomly stops, I want the Level3 monitor to go nuts -- precisely because it cannot route around the issue. We had an issue a while back where TWTelecom was blackholing our traffic and it took ~10 minutes to detect what and where the problem was; having another device elsewhere on the same network would have been invaluable.
