    • Updated

    Manually purging all caches or individual objects from Platform CDN

    Important Note: These instructions clear content from Platform CDN only. To replace it with fresh content ensure that the content has also been purged from Acquia Varnish first.


    First step: Retrieve the service_id and token

    Run the following commands to SSH into your environment and use drush9 to retrieve the service_id and token:

    ssh sitename.environment@sitenameenv.ssh.prod.acquia-sites.com

    Your ssh url can be found in your Acquia Environment Information Section in the Cloud UI

    drush9 --uri="https://www.example.com" state:get --format=json acquia_purge.platform_cdn


    The output will be similar to the following:

    {
   "acquia_purge.platform_cdn":  {
      "vendor": "fastly",
      "service_id": "1MFG0lmpFvMCoiziPbKLBB",
      "token": "NFA6ZgZaQfC1u1117WJuu3cVbf0ChlDY"
   }
}

    Second step: Purge Platform CDN 
    Purge Platform CDN by running the following curl command with the token in the header and the service_id in the URL path as shown in the following example:

    curl -X POST -H "Fastly-Key:<Platform CDN Token>" -H "Accept: application/json" https://api.fastly.com/service/<Platform CDN Service ID>/purge_all

    For example:

    curl -X POST -H "Fastly-Key:NFA6ZgZaQfC1u1117WJuu3cVbf0ChlDY" -H "Accept: application/json" https://api.fastly.com/service/1MFG0lmpFvMCoiziPbKLBB/purge_all


    Before manually purging the Platform CDN cache, purge your Varnish cache to ensure cache consistency.
