Tiers priced 2

2 of this model’s published tiers no longer come from the vendor. The provider stopped publishing those keys and we did not stop publishing a value for them, so the next source down the trust order supplies the number: it is real and it is sourced, but it is not the provider’s own rate and the provider may no longer sell at it. Each one is marked in the table. See source handovers.
