On: Post mortem of a failed HackerNews launch

1. So nginx didn't cache because of cookie?

2. Isn't swapping bad? I don't think I've ever had a situation in which swap more than say 100MB was helpful. Once the machine starts swapping, a bigger swap just prolongs the agony.

3. If you couldn't ssh, why didn't you just reboot the machine?

Edit:

1. What did you use for the graphs?

2. What is the stack?

We use DataDog - http://www.datadoghq.com/ . It’s a statsd, graphite manifestation but with much more capabilities.

Stack is Python, Django, PostgreSql, Redis, Memcache etc.
