The politics involved can be interesting.

Sometimes, your equipment is fine, but your peer has a 1GB card in their peeing router instead of the 10GB they promised, and they need time to budget the upgrade.

Sometimes, your peer is handing off packets fine, but their peer is dropping some or all of them - and it's difficult to get someone halfway across the world to spend money for you when you're not their direct customer. Influence falls off at an inverse square of the degrees of separation, or so it feels.
