If an HN post with 10 upvotes makes your site go down, do you really have the right to tell people how to write code?
1.) that's more a statement of the hardware than the software, and they may be running on a tight budget (I have no idea b/c I can't see the site).
2.) If it has 10 upvotes, then that probably means that a significantly higher # of people are trying to view the site so they can decide whether or not to vote, which is not a trivial situation if you aren't prepared for it.
The above comes across as outright dismissive.
