Some Brazil government websites/apps have a "virtual queue" system.

During traffic surges, such as when government allows people to withdraw part of their unemployment fund for one reason or another, the site/app loads normally but display a page placing you in a queue with a dynamically updated ETA, usually several minutes or hours.

Example (news article in Portuguese): https://epocanegocios.globo.com/economia/noticia/2023/07/dis...

A weird way to rate limit... I guess it perfectly emulates the real life experience of waiting in line for hours in government branches.
