99.9999999% up time!

Just finished watching a good video by Bryan Hunter titled Erlang for C# Developers where he told a great story about the first project Erlang was used in inside Ericson and how they managed a Nine Nines uptime with that project.

For anyone who’s wondering what ‘Nine Nines’ means, it means the service is available 99.9999999% of the time or, a total of 32 milliseconds of downtime a year! Unbelievable!
