There are many scenarios in which you might prefer running a site within an International Region rather than the default US. Common use cases include:
Four regions are available when creating a new site:
Pantheon sites have all site resources in the region in which it was created. This includes application and database containers, Redis cache servers, Apache Solr index servers, and a distributed filesystem and request router.
Automated and manual backups of all site components (code, database, and files) are stored in the EU and created by job workers also running in the EU. Additionally, any database or file clones between site environments are run by EU job workers.
Localized, EU-specific Disaster Recovery is also available.
With this set of EU-specific resources, now you can run WordPress or Drupal sites on Pantheon and meet the European Union's legal, regulatory, or data sovereignty requirements.
Create a new Site from the Dashboard and select the Region:
For example (replace
My EU Site Name,
My Organization Name accordingly):
terminus site:create my-eu-site-name "My EU Site Name" "WordPress" --org "My Organization Name" --region eu
terminus site:create --help for more information on the options and values used in this command.
If you'd like help migrating your site between regions, our Professional Services Migrations team is available.
Use the Dashboard to see the Pantheon Region in which the site is hosted:
United Statesby default, or the name of the International Region in which the Site is hosted.
You can also get this information via Terminus.
In the following sections, assign
$SITE or replace it in each example with your site name or UUID.
terminus site:info $SITE
terminus site:list --org "My Organization Name" --fields name,region
grep to expose the
x-served-by response header or
AMS to verify whether the Amsterdam origin shield was used as expected (replace
curl -Is https://example.com | grep x-served-by
curl -Is https://example.com | grep AMS
The output should look something like:
curl -Is https://dev-rachel-whitton-eu2.pantheonsite.io | grep x-served-by x-served-by: cache-ams21041-AMS, cache-jfk8127-JFK
Yes, however you must migrate your existing site to a new site that was configured for the new region during creation (as described above).
