Provider Network Model
Your own private address range on a shared platform: per-zone subnets, route tables, private paths to managed services and boundary filtering. Probed because the network plan is what nobody revisits.

page 2 of 2As networks keep attaching to a transit hub, which ceiling bites before bandwidth does, and how does it show up?
basics
~20 sThe route-table entry limit bites first. Entries scale with networks multiplied by the prefixes each announces, not with traffic, so a hub and its spokes hit a ceiling while bandwidth is still idle — and the symptom is partial reachability for the newest ranges.
A nightly batch's calls to one partner endpoint fail at peak while bandwidth stays low — what has the shared gateway run out of?
basics
~20 sFree source ports for that one destination pair. An address-translating gateway holds an entry per flow, and with the destination address and port fixed only the source port varies, so simultaneous flows to a single endpoint hit a ceiling long before bandwidth does.
The dedicated circuit is finally delivered and the ledger must move off the tunnel — how do you sequence a cutover whose rollback is real?
basics
~20 sRun both paths live and move traffic by changing preference, never by tearing the old one down. Shift a low-risk flow first, soak it against agreed signals, then the ledger — and keep the tunnel configured, sized and up, because that is what rollback consists of.
