Lessons learnt from reading post mortems–Dan luu

A really good article form Dan Luu of describing the knowledge he has gained from reading post mortems. One key takeaway – hardware errors and developers can cause issues, but to really flatten your infrastructure you need a config change.

I should also acknowledge my debt to Dan for a) giving me the idea for this site and b) providing a “seed” list of outage reports that I could used to populate this site.
