Working with CDN services

Once you create a CDN service, you can edit and activate new versions of your Fastly services that include refinements and updates to your configurations. The web interface also allows you to do other things with existing Fastly services, like compare them to each other, deactivate or reactivate them, and delete them.

Before you begin

Before you create your first Fastly service, be sure you understand how services and versions work and service creation limits. You'll also need to understand the Fastly web interface controls before using them to work with your Fastly services.

Creating a new CDN service

You can create new CDN and Compute services through the web interface. Use the steps below to quickly create a CDN service that uses standard defaults common to many customers. If you prefer to create a draft service immediately, the Skip and go to service configuration link will automatically create a draft version of a new service with no recommended defaults.

1. Log in to the Fastly web interface.
2. Click New service at the top right of the page, just below the primary navigation controls.
3. In the Service name field, enter a descriptive name for your service (e.g., My Example Website Service).
4. In the Domain field, enter the name of the domain you want Fastly to use to route requests to. Our guide to working with domains provides additional details.
5. In the Host field, enter the name of the host you plan to use as the backend or origin for your site. Our guide to working with hosts provides additional details.
6. Review the Recommended settings that are enabled by default for your service and decide whether or not to disable them by clicking the appropriate setting switch to Off.
   • The Override default host setting enables host override at the origin level. Many customers creating services specify an override host at the same time, especially when using an origin that requires a specific hostname to be passed to it.
   • The Default compression setting enables automatic compression using a default compression policy. Automatic compression on our edge servers can help you reduce the size of your assets so traffic can flow faster.
   • The Force TLS & HSTS setting enables the HTTP Strict Transport Security (HSTS) security enhancement specification through Fastly and forces modern web browsers to communicate only via the TLS protocol. If you leave this default setting enabled, be sure to create a TLS certificate for use with your domains. For more information, check out our TLS documentation.
7. Click Activate. Your service will be created using the service name, domain, and host you specify and the default settings you've left enabled.
8. Test your service configurations by opening https://www.example.com.global.prod.fastly.net in a new browser window, replacing www.example.com with your own website's domain name. Your website should appear, though it may take up to 60 seconds for new configuration settings to take effect. You can continue to explore various configuration settings for as long as you like before starting to serve traffic.
9. Once you've reviewed everything and are ready, complete your service setup and start serving traffic through Fastly by setting your domain's CNAME DNS record to point to Fastly.

Editing your services

You might want to edit a version of an existing service to do things like:

• change the amount of time information is retained in cache memory for a service
• configure a service to temporarily serve stale content should your origin server need to be unavailable for an extended period of time (for example, taken offline for maintenance)
• decrease the amount of time Fastly will wait for your origin server to respond to a request for content

Editing and activating versions of services

Fastly locks versions of services you've already activated to make rollbacks safer and provide version control. You can duplicate (clone) any existing service version, active or inactive, and edit that cloned version. You must activate new versions of services to deploy their configurations. Configuration changes are never automatically activated.

To make changes to a service and activate a new version, follow the steps below:

1. Log in to the Fastly web interface.
2. From the Home page, select the appropriate service. You can use the search box to search by ID, name, or domain. You can also click Compute services or CDN services to access a list of services by type.
3. From the Edit configuration menu, select the appropriate service configuration action:
   • Select Clone version [version number] (active) to clone the active version of the service for editing.
   • Select Edit version [version number] (latest draft) to edit the latest draft of the service.
4. Click Activate. The new version of the service is activated and appears in the event log.

Viewing all services

You can view all the services associated with your account or filter them to show only specific types of services.

Viewing a complete list of services

To view all your services once you're logged in, click either Compute services or CDN services in the Your services card of the Home page to display a list of your services of a particular type. Clicking on each column in the displayed list will sort the entire list based on that content type.

If you have a lot of services, you can view a condensed version of the list by clicking the icon with three lines above the list of services.

Viewing a subset of all services

You can filter your list of services to show services that are active or inactive, or that you've designated as favorites. To filter your services, select the appropriate filters from the Filter menu above the list of services:

The filters you've applied to the list will appear as oval shapes above the list of services. You can remove a filter at any time by clicking the x on any filter or the Clear filters option.

Switching between services and service versions

To switch between services associated with your account, follow these steps:

1. Log in to the Fastly web interface.
2. From the Home page, select the appropriate service. You can use the search box to search by ID, name, or domain. You can also click Compute services or CDN services to access a list of services by type.

3. From the Service summary or Service configuration page, click the switcher to the right of the account name and ID.

   

4. Select the appropriate service from the list that appears.

To switch between versions of a specific service, follow these steps:

1. From the Service configuration page, click the switcher to the right of the version number.

   

2. Select the appropriate version from the list that appears.

Deleting a service

Fastly allows you to delete any service you create, along with all of its versions. Fastly does not offer a way to delete specific versions of a service, however. Service versions are meant to be a historic log of the changes that were made to a service. To undo changes introduced by a particular service version, you can always go back to a previous version and reactivate or clone a new service version based on any old version.

To delete any service along with all of its versions, follow the steps below:

1. Log in to the Fastly web interface.
2. From the Home page, select the appropriate service. You can use the search box to search by ID, name, or domain. You can also click Compute services or CDN services to access a list of services by type.
3. From the Options menu, select Deactivate.
4. Click Confirm and deactivate to confirm you want to deactivate your service and acknowledge that you no longer want to serve traffic with it.
5. From the Options menu, select Delete and then click Confirm and delete to delete the service.

Other things you can do

In addition to creating or editing services, you can view all your services, rename them, compare versions of them, deactivate or reactivate specific versions of them, and delete them.

Renaming services

To rename your service, follow the steps below:

1. Log in to the Fastly web interface.

Getting help with accidental service deletions

Services can be deactivated or deleted. Deactivated services can be reactivated at any time, but once they've been deleted you must contact Customer Support to have them restored. When sending your request, remember to include:

• your customer ID
• your company name
• your service ID (the name of the service you want restored)

Customer Support will notify you when your service has been restored.
