I believe in glitch monsters. They prey on start-up websites, especially when they launch.
Simply no matter how many times we all double and triple check, glitch monsters, sharing the same bloodlines as vultures, are far too ambitious to break or tear apart your prime opportunity.
This time it wasn't the glitch monsters, it was me.
My glitch is called underestimating.
I hosted a launch party to celebrate the launch of www.neverfold.com (a closet solution where you never need to fold your laundry).
People were tweeting and facebooking about the launch party. I proceed to hit the 'launch' button only to find myself totally embarrassed while everybody watched my website go from live to nothing but errors.
Turns out I picked a database with 20-max connections. Stupid. Fortunately, I am using Heroku so upgrading from 20 to 500 was a breeze!
"At least it was a good problem to have." said my friends at the party.
Morale of the story: Go big and downgrade as needed!
