Key Questions Answered
What is geo-blocking and why is it used?
Geo-blocking is an industry-standard practice that restricts access to specific content based on a user's location. It is used to comply with local laws and regulations, ensuring that users see content appropriate for their region.
How does Pinterest handle geo-blocking requests?
When a geo-block or unblock request is received, Pinterest logs the media as 'in progress', creates a job to locate media variants, updates metadata in S3, purges the CDN, and finally logs the action as 'successful' in Kafka.
What happens when a user requests blocked content?
If a user requests content that is geo-blocked, they receive an HTTP 451 status code, along with a brief explanation of the reason for the block, such as copyright or licensing issues.
