October 27, 2020

Added a new tutorial: Setting up an HTTP-to-HTTPS redirect

October 26, 2020

Cloud CDN can now cache more response codes, including common error codes such as 404 (Not Found), 301 (Permanent Redirect), 302 (Temporary Redirect), and many others.

If you are sending valid cache directives from your origin, you do not need to make any changes to benefit from this.

You can also set (and override) per-status code TTLs by configuring negative caching as of gcloud SDK 316.0.0.

October 01, 2020

Added a new tutorial for delivering HTTP and HTTPS content over the same hostname when using Cloud CDN. While many browsers enforce the use of Transport Layer Security (TLS) and disallow non-secure content delivery, there are still use cases where non-secure delivery and secure delivery must be allowed over the same hostname.

September 29, 2020

Improvements to Cloud CDN's request collapsing behavior: If your deployment serves large objects, these improvements reduce origin load during revalidation and cache fill. Live video workloads will see the largest benefit. For more information, see Support for byte range requests.

September 14, 2020

Cache Modes, TTL overrides and custom response headers are now supported on backend buckets and backend services, and are available in beta.

Cache modes allow Cloud CDN to automatically cache static content types, including web assets like CSS, JavaScript and fonts, as well as image and video content.

TTL overrides support fine-tuning how long Cloud CDN caches your responses, and custom response headers introduce a new {cdn_cache_status} variable that is populated with the cache status response.

External HTTP(S) Load Balancing now supports setting custom response headers on backend buckets and services. This feature is available in beta.

Custom response headers make it easier to set common web security headers and/or override response headers from your application at the load balancer.

September 09, 2020

September 02, 2020

Reduced cache fill pricing from Cloud Storage, Compute Engine, and external origins by up to 80% starting September 1st.

Google Cloud has also removed cache-to-cache fill and cache invalidation charges.

July 13, 2020

Added a new setup guide for custom (external) origins with Cloud CDN and external HTTP(S) Load Balancing.

June 10, 2020

HTTP(S) Load Balancing with Cloud CDN logging is available in General Availability.

May 29, 2020

To help you get started quickly, added two new examples for setting up Cloud CDN:

May 01, 2020

Added a new Features page that summarizes all Cloud CDN capabilities.

April 17, 2020

Cloud CDN request logs now include a cacheId field, which captures the location and cache node the client connected to. A cacheId of LHR-1209ea83 indicates a client connected to an edge cache near London, with 1209ea83 representing the opaque ID of the cache instance their response was served from.

Location codes map to ⁠IATA codes. The cacheId field can be found within the jsonPayload object in each log entry.

April 15, 2020

Signed Cookies are available in General Availability. Signed Cookies complement our existing Signed URLs functionality by allowing you to sign a URL prefix and issue a cookie to a client, avoiding the need to sign content on a per-URL basis when protecting media or other content cached by Cloud CDN. Support for authorizing a URL prefix is extended to Signed URLs as an alternative signing scheme.

April 09, 2020

TLS v1.3 is now enabled by default for all external HTTPS load balancers, SSL proxy load balancers, and Cloud CDN. Note that this change doesn't apply to internal HTTPS load balancers or Traffic Director.

TLS v1.3 supports modern ciphers with forward-secrecy as a baseline and, critically, reduces the number of round trips required to establish a TLS session, which directly improves performance seen by your end-users.

Clients that support TLS v1.3 include Chrome, Chromium-based browsers, and Android. These clients automatically negotiate TLS v1.3 without requiring any changes. Clients that do not support TLS v1.3 are unaffected.

March 25, 2020

Cloud CDN custom origins is available in General Availability. You can now use Cloud CDN's distributed edge caching infrastructure to connect to an origin hosted outside of GCP, such as on-premises or in another cloud.

February 10, 2020
