[Sephiroth]

I don't know how this discussion has backed itself so far into a corner. Speedtests on the VM network are influenced by:

- Congestion (if any) at the optical node
- Congestion (if any) at the line card
- Congestion (if any) at the CMTS itself (unlikely)
- Congestion (if any) in the core (rare but not unknown)
- Congestion (if any) in the VM backbone (rare and occurs if there is a routing problem elsewhere)
- Congestion (if any) at the peering point (deffo possible)
- Congestion (if any) at the speed test server (e.g. Maidenhead - so well known)

Simples.
