Tier 1 has enough peering relationships with enough other Tier 1 networks that they can always buy temporary transit privileges over an existing link.
Every peering agreement I've seen has language to the effect that an entity can't both be a transit customer and a peer. Even if allowed, the temporary transit privileges would need to be provisioned and turned up which isn't going to happen instantaneously.
Tier 1 means you don't buy transit, no?
