This is an in-progress document about the kinds of patterns we see or use when designing systems. The author warned me that it’s a work in progress and maybe not ready for prime-time, but I think this is exactly the time when I should get it in front of your eyes.

I’d love your help growing this list. If you know of a name that is missing from the list please send me a tweet with the name and a short description of it and I’ll include it in the list with a link to your tweet

This two-part series uses a narrative case study format to show how SLOs can be misleading. You might have great numbers, but what are the numbers actually measuring?

  • A major US oil pipeline
    • The pipeline was targeted by a ransomware attack.
  • GasBuddy
    • This app for finding gasoline prices seems to have been impacted by a flood of user traffic driven by the US oil pipeline outage. In fact, their front page seems to be very slow for me as I write this.
  • Salesforce
    • The outage was widespread and even affected their status page.
  • eBay
  • Microsoft Outlook
