Well, the good news is that the teething problems have been sorted and the service is finally working. There are many lessons to learn as to why this took so long to resolve, and we are waiting for details of the underlying cause from BT.
Obviously we provided details of the fault, packet dumps, and our views on what seems to be the underlying cause to BT. I hope this was helpful to them in resolving the issues.
However, it makes for a very interesting service.
I am pleased to say that we have managed to set up fall back routing for this customer. We are testing the link state on each of our connected routers, and allowing fall back to conventional broadband if the link drops. We can even set up 3G fall back as a third tier for this now.
This provides a high availability fixed price Internet access service to a small ISP in Basingstoke, and we now have a happy customer.
As I understand it, the roll out for this is to have all the exchanges that do FTTC and have Ethernet access nodes covered by the end of the year (around 500 exchanges).
