Ubuntu Rate Limits

Canonical does not publish per-second numeric rate limits for the Ubuntu Pro Contracts API, Livepatch API, or related services on its public terms / pricing pages. Operational throttling exists at the CDN / edge but is not documented as a fixed quota for end users.

Specific request-rate ceilings are not published; access is gated by machine token / contract token rather than a public per-second quota.

Policies

Token-Scoped Access

Ubuntu Pro Contracts and Livepatch APIs are accessed via per-machine tokens issued at attach time; throttling, when it occurs, is per-token at the edge.

Backoff

Apply exponential backoff with jitter on transient errors; no specific Retry-After timing is documented publicly.
