In my travels around the crazy web, I’m amazed how many web sites still use a boring server-generated 404 error page instead of a custom 404 error page. Even large brands with deep pockets aren’t immune to the dreaded vanilla dead end.

Thankfully, there are lots of clever web designers out there who recognize that there’s no excuse for un-inventive 404s. Web site usability can be fun!. This week’s Fast Five pays homage to them and their entertaining ideas for custom 404 error pages.

Here’s this week’s Fast Five – Five Clever Custom 404 Error Pages:

1) Mint.com – This page combines humor with helpfulness. Not only does it make a joke about the missing content, but it offers up some useful alternative links in a pleasing visual format. No blame, no suggestion that the searcher was at fault. I like that.

2) BlueDaniel.com – This is my current favorite 404. Not only is it Flash based – which I’ve not seen before in a custom 404 – but it’s exceedingly cool. The powerful visuals and sound of an underground train station are bang on target for a motion picture design company. This page alone would probably win them new business.

3) Heinz.com – So an empty ketchup bottle might be a little predictable, but what I like best about this page is the intuitiveness and the very clear calls to action. Did you try searching? Perhaps one of these links will help? Perfect.

4) Mashable.com – Again, another humorous yet helpful Custom 404 page. This one uses the missing sock analogy, combined with a giant call to action in the form of an internal search field. They also keep the main nav menu at the top of the page in case you’d rather resort to standard navigation.

and finally…

5) ApartmentHomeLiving.com – Being in New Zealand, this custom 404 page caught my eye straight away. You can’t really go wrong with a sheep on a toilet. Apart from using an amusing mouseover effect, this page steers lost visitors back to the homepage or to the regular navigation menu. Sorted.

What’s YOUR fav custom 404 page? Would love to hear about it in the comments.
