Hi,

We recently launched AMP after a year of working on it (see https://www.androidpolice.com/2019/08/31/android-police-now-supports-google-amp/?amp), but realized that content updating doesn't work, and we need a little help.

https://www.androidpolice.com/.well-known/amphtml/apikey.pub was originally not served as plaintext, but that's been rectified is. It's possible that all we need is some sort of flush so that Google ingests it.

1. https://developers.google.com/amp/cache/update-cache#update-rsa-keys states that to update the key, we can also ping https://example-com.<cache.updateCacheApiDomainSuffix>/r/s/example.com/.well-known/amphtml/apikey.pub which in our case should be https://www-androidpolice-com.cdn.ampproject.org/v/s/www.androidpolice.com/.well-known/amphtml/apikey.pub, but that's a 404.

2. I tried joining https://amphtml.slack.com to ask the questions, but it seems to be only for @google.com users. Found https://bit.ly/amp-slack-signup and submitted a request. Hopefully that's still the right way to get in.

3. Finally, the request to dump cache I'm trying to make is something like https://www-androidpolice-com.cdn.ampproject.org/update-cache/c/s/www.androidpolice.com/2019/08/31/android-police-now-supports-google-amp/%3famp?amp_action=flush&amp_ts=1567319166&amp_url_signature=Hkpfwk1YoewxjBAyaDEtIJ2EB9PWqBY_CeuuICQKmaPkCZ56zKdE9ROoiWdYfWaE-iUJjp2bX_cyHXl4jOqAkeKXeoJNjXwISSohPz_6E7nB4e94iLPxEGojDsEqvZ4ybSRBlsip1NNI5vXGBZKIPv-28GeoDtTGCyVxvPwnJRTn0POkQRfbWlM_hcLq9QlfVqV9w9jjm2TJ6K7Vk3NnsEsFqtsZsAsBbjYUVwiuxnCFNgyIljs8izLxySkWV8Ks6Z5ESMqVTruhSinc1iHB-bRuFQYzvM8JoiS9KoiWWRg4RgDHjNs2VKTx88kescVKgxl5BvwvgyOxKG7J0xAmK1, but it returns

403. That’s an error.

Your client does not have permission to get URL /update-cache/c/s/www.androidpolice.com/2019/08/31/android-police-now-supports-google-amp/%3Famp?amp_action=flush&amp_ts=1567319166&amp_url_signature=Hkpfwk1YoewxjBAyaDEtIJ2EB9PWqBY_CeuuICQKmaPkCZ56zKdE9ROoiWdYfWaE-iUJjp2bX_cyHXl4jOqAkeKXeoJNjXwISSohPz_6E7nB4e94iLPxEGojDsEqvZ4ybSRBlsip1NNI5vXGBZKIPv-28GeoDtTGCyVxvPwnJRTn0POkQRfbWlM_hcLq9QlfVqV9w9jjm2TJ6K7Vk3NnsEsFqtsZsAsBbjYUVwiuxnCFNgyIljs8izLxySkWV8Ks6Z5ESMqVTruhSinc1iHB-bRuFQYzvM8JoiS9KoiWWRg4RgDHjNs2VKTx88kescVKgxl5BvwvgyOxKG7J0xAmK1 from this server. (Client IP address: 73.189.194.95)

Invalid public key due to ingestion error: Invalid Content

That’s all we know.

Presumably, this points to an inability to read the key?

4. For AMP urls that end with ?amp, do we need to send a request to https://example-com.<cache.updateCacheApiDomainSuffix>/update-cache/c/s/example.com/article%3famp?amp_action=flush... or https://example-com.<cache.updateCacheApiDomainSuffix>/update-cache/c/s/example.com/article?amp&amp_action=flush...?

5. Regarding cache, do I understand it correctly that if we don't send a max-age cache-control header, the cache will never be updated, but if we do, it'll be updated once the max-age runs out without having to ping update-cache? Or do we still need to update-cache for every time we edit the content?

Thank you.
