15 minutes :)
We really jumped the gun and it is something I probably shouldn't have done but I never ever anticipated the kind of response it got.
By morning the server was a molten slag heap, I didn't even know because I was sleeping.
We mailed about 1,000 people that we were trying something new after building it, what we didn't anticipate was that they in turn mailed all their friends and so on.
A bit of performance testing before launch would have definitely helped.
The odd thing is, every time you do a lot of performance testing you end up with a dud :)
