I had a discussion with them about a point to point circuit last year and ran into some weirdness around how burstable it would be for specific IP to IP streams as our use case was cheap circuit / high speed data replication between given endpoints.  The sales rep was suggesting to me that I’d see specific source/destination IP pairs capped at 2gbps regardless of circuit speed, which suggested to me it was not actually a point to point wave but some type of encapsulated service.  We didn’t get into whether it was usable for non-IP, etc.
