# Access Control Limit (ACL)

Explanation:

To ensure availability for all and thus equal opportunities, the RRI has an access control limit.

## Request Counting

Every request is counted, whether valid or invalid.

## Throughput:

- RRI-Live, 04:00 - 02:00 CET: 2000 requests / 60 seconds

- RRI-Live, 02:00 - 04:00 CET aka purge phase: 200 requests / 60 seconds

- RRI-Rush, 00:00 - 24:00 CET aka one full calendar day; 2000 requests / 60 seconds

## Blocking

The number of requests must not exceed the limit in the defined time interval.

If the limit is exceeded, error code 55000000002 issued.

- If the limit is exceeded: 120 seconds blocked

  - Unblocking: The request volume was below the maximum in the last 120 seconds (currently the limits are 2000 or 200 requests).

  - Continued blocking for 120: The request volume was above the maximum in the last 60 seconds.
