Zayo Rate Limits
Zayo publishes no rate limits and emits no rate-limit signal. This is a measured zero, not an unchecked one: every one of the 30 operations in Zayo's own OpenAPI was examined and none declares a 429 response, a RateLimit-* or X-RateLimit-* header, or a Retry-After header, and the Getting Started page's error table stops at the 4xx/5xx range description without mentioning throttling. The practical consequence is that a client has no runtime budget signal at all — it cannot learn its remaining quota, and cannot be told when to come back.
Zayo Rate Limits is the machine-readable rate-limit profile for Zayo on the APIs.io network, conforming to the API Commons Rate Limits specification.
The profile also includes 2 backoff/retry policies defined and response codes documented for throttled and note.
Tagged areas include Fiber, Network, Telecom, and Rate Limiting.
