How long does DNS propagation typically take after configuring a custom domain for Blogspot, and what does it mean?

DNS propagation is the process by which changes made to your domain's DNS records are updated across the global network of DNS servers. It can take anywhere from a few minutes to 48 hours, though often it's completed within a few hours. During this period, your custom domain might not immediately resolve to your Blogspot blog for all users, as different DNS servers around the world update at varying speeds. Patience is key during this waiting period.
