10 ms is good, but not seen an ISP with hops that are not unreachable. The cause and effect of that is what we should be getting to the bottom of.
Shouldn't have any effect. The unreachable ones aren't responding to the tracert requests directed to them, and some of the slower ones respond slowly to such requests. However, they should forward tracert requests targetted at further down the chain as fast and reliably as they forward anything else. If they are slow at forwarding that will affect all traffic, and show up correctly as longer latency times to the points further down the chain.
On another point, I've just realized that when the phone price increase comes through I have the chance to break my Plusnet broadband contract as well as the phone one, should I choose to do so. That means that my decision time will be closer than I had expected (soonish rather than early next year).

Recently moved from BT Infinity 2 to PlusNet. Very happy so far.
