      • Manage stats
      • Manage server backup configuration
      • Terminate (delete) accounts
      • Any server-wide issues

  2. How to Debug DNS Issues
    • This video covers:
      • How does DNS Work (in a nutshell)?
      • How to Diagnose DNS Issues
    • There is no single answer to all problems.
    • Understanding how the system works is the key.
    • Your customers must enter your nameserver names and IP addresses with their registrar.
    • You do not want to change your nameservers much, because it inconveniences customers.
    • Check glue records first, since if they are incorrect, nothing else will work.
