I've decided to get transit from provider B independently of A, so I don't =
create a conflict of interest as mentioned below. However I think that I w=
ill have to use provider A's dark fibre network to connect to both peerings=
. Provider A tells me that they will use different routes and different en=
try points to get to their peering and separate routes, entries to get to B=
's peering. As they own the datacentre and can probably provide the bests =
costs for getting into the datacentres where the second transit provider is=
, I think I will have to use=20
I should mention there are no transit providers on net at the datacentre fa=
cility which has been acquired by the business. I suspect it will be cheap=
er to get the cross connects to where the transit provider is from provider=
A, (did I mention provider A owns the datacentre?). I know I'll be sacrif=
icing some resilience by using A's network to get to both Internet services=
, however I think I will just have to outline the risks to the business and=
go with it. Moving datacentres isn't an option and as long as I understan=
d exactly what resilience I sacrifice by getting A to provide all the cross=
connects, I can explain that to the business.
