Frequently Asked Questions

What is a parser-blocking resource?

A synchronous script or stylesheet that forces the browser's HTML parser to pause until the resource is downloaded and executed.

How do third-party dependencies impact reliability?

If an external script, font, or analytics CDN experiences an outage or latency spike, dependent page features can slow down or fail.

What are initiator chains?

An initiator chain is the sequence of requests that caused an asset to download—such as an HTML document loading a CSS stylesheet that imports an external font.
