Why didn't my computer reconnect?
There was an electricity cut here, it came back soon. Currently where I am the computer is in other flat & I ssh to it from laptop. After the electricity was back, I tried sshin'g to my computer but it timed out everytime.
Long story short, the computer was not turned on! Not a big thing but I was surprised that I didn't think of this, whole time I was thinking it was poor puffy's fault.
