  • Slow upload
  • Slow download
    • This could be that your kids are watching a show and your partner is on a zoom call
  • High latency
  • Intermittent

  • Show loading UI for everything, but after X seconds
  • Page transitions on SPAs
  • Form switches - enter country, get list of provinces/shipping/whatever

11:58 - Account for XHR failures

  • Sometimes I'm in a loading state forever
  • State machines will account for this
