note: Page describes Fastly's Edge Rate Limiting product (customer-configurable rate counters and penalty
  boxes), not rate limits imposed on consumers of a Fastly API. Numbers appearing (1s/10s/60s window sizes,
  a '100 requests per second over a 10 second window' illustrative example, up to 10% under-counting,
  2 minute minimum penalty box TTL) are configuration options or examples rather than provider-imposed
  limits. No rate-limit headers or exceeded status documented.
