Quotas and limits

This document contains current content limits and request quotas for the Traffic Director API. This page will be updated to reflect any changes to these restrictions and usage limits.

URL map limits

URL maps can contain up to 50 path and host rules. Exceeding this amount results in an error like the following example:

Value for field 'resource.hostRules[0].hosts' is too large:
maximum size 50 element(s);actual size 57.

Managing quotas

Traffic Director enforces quotas on resource usage for various reasons. For example, quotas protect the community of Google Cloud users by preventing unforeseen spikes in usage. Quotas also help users who are exploring Google Cloud with the free tier to stay within their trial.

All projects start with the same quotas, which you can change by requesting additional quota. Some quotas may increase automatically based on your use of a product.

Permissions

To view quotas or request quota increases, Identity and Access Management (IAM) members need one of the following roles.

Checking your quota

Console

  1. In the Cloud Console, go to the Quotas page.

    Go to Quotas

  2. To search for the quota that you want to update, use the Filter table. If you don't know the name of the quota, use the links on this page instead.

gcloud

Using the gcloud command-line tool, run the following command to check your quotas. Replace PROJECT_ID with your own project ID.

      gcloud compute project-info describe --project PROJECT_ID
    

To check your used quota in a region, run the following command:

      gcloud compute regions describe example-region
    

Errors when exceeding your quota

If you exceed a quota with a gcloud command, gcloud outputs a quota exceeded error message and returns with the exit code 1.

If you exceed a quota with an API request, Google Cloud returns the following HTTP status code: HTTP 413 Request Entity Too Large.

Requesting additional quota

Request additional quota from the Quotas page in the Cloud Console. Quota requests take 24 to 48 hours to process.

Console

  1. In the Cloud Console, go to the Quotas page.

    Go to Quotas

  2. On the Quotas page, select the quotas that you want to change.
  3. At the top of the page, click Edit quotas.
  4. Fill out your name, email, and phone number, and then click Next.
  5. Fill in your quota request, and then click Done.
  6. Submit your request.

Resource availability

Each quota represents a maximum number for a particular type of resource that you can create, if that resource is available. It's important to note that quotas do not guarantee resource availability. Even if you have available quota, you can't create a new resource if it is not available.

For example, you might have sufficient quota to create a new regional, external IP address in the us-central1 region. However, that is not possible if there are no available external IP addresses in that region. Zonal resource availability can also affect your ability to create a new resource.

Situations where resources are unavailable in an entire region are rare. However, resources within a zone can be depleted from time to time, typically without impact to the service level agreement (SLA) for the type of resource. For more information, review the relevant SLA for the resource.
