Checked system Fri night, Spitfire line failed under load, one "Be" line down. Ran system on one "Be" line. When checking to www.bbc.co.uk there were ping timeouts every 4-5 seconds, so users would have been getting a slow service.
There are two failure modes of "Be" routers, one where the router comes back after power cycling - one where it does not. At the moment we have the latter. Neither are acceptable.

I think the failures are down to the routers. I rang "Be" tech support to check if either failure mode is known / common by tech support, thinking they might be able to indicate whether it is worth replacing the "Be" router with the same model (this never normally happens) or with a more reliable brand of router (this happens whenever the line is under a lot of stress).

One thing occurs to me that if the BBCi player becomes popular amongst Charing cross residents we will be have to switch back to some sort of policy based routing.

Checked system again this morning seemed to be running OK.
