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.

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.

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.
