How can a CDN fail to retain an IP address, at least for the purposes of knowing where to send the response? The ruling doesn't say that Google stored the IP, causing the issue, but merely that the user's IP showed up in a packet sent to Google.

Storing an IP address in RAM until you have sent the response is _obviously_ a technically necessary use of personal data.

But who knows what else google does? The "privacy info" for site owners using google fonts says nothing about what they use any collected data for.

When you share personal data about your visitors with a data processor, you need an agreement that specifies how that data is treated.
