How often does Atlassian check geo-location access data for Cloud service like Jira?

[m93]

According to information on page: Cloud hosting infrastructure 

Localized data,
better performance

Our cloud hosting infrastructure for Jira Software, Jira Service Desk, and Confluence includes AWS regions across the United States, Germany, Ireland, Singapore, and Australia.

Our platform optimizes where customer data is located based on origin of access, ensuring more reliable performance and reduced latency. As an example, if the majority of users access your organization's Jira or Confluence cloud instances from Europe, then their data will be migrated to and stored in Europe.

My question is: How often such "origin of access" is being checked? Day, week, month?
