This is awesome if you haven’t seen it: MailChimp’s Annual Report for 2012.
Some cool data:
- 9512 commits to the app and site (that’s 26 for each day of the year!)
- 3.5 hours of planned and unplanned downtime for the year
- 1.4 million new users signed up
- 281 servers running in total from 6 data centres
- 132 employees (only, considering they get about 1100 support tickets daily)
- 29800 shirts mailed (unfortunately I never got mine :( )
Love the transparency.
