Twitter’s Performance Problems Explained By a Twitter Engineer

What happened that caused this week’s Twitter issues, wrote engineer Jean-Paul Cozzatti, is that the engineering team made three critical mistakes:

  • The team put two important, fast-growing, high-bandwith components on the same segment of Twitter’s internal network.
  • The network wasn’t being monitored the way it should have been.
  • The internal network was also temporarily misconfigured.

The pressure on the team to be ready for the World Cup must have been huge. This will likely rival any past global tweets Twitter has scene.
