Sooner or later all websites run into trouble (even Google) or have to perform maintenance that takes them offline. However, there is a big difference between how different websites handle the resulting error or maintenance pages that will have to be shown to the user. Some lighten the mood with jokes, some are dry and to the point, and some drop the ball completely.

We make our living here at Pingdom by monitoring websites for problems, so we tend to stumble across more of these error pages than most people do. This post includes error and maintenance pages for 24 of the most popular Web 2.0 services out there. While two of them can definitely be considered examples of what NOT to do, the other 22 are here to give you plenty of inspiration and hopefully put a smile on your face.

We have divided them into three categories:

• The fun (or very strange) ones
• The to-the-point ones
• The “non-existent” ones (i.e. the bad examples)

If you’re a frequent user of these services, you are bound to recognize some of the screenshots below, although we tried to stay away from the most obvious ones (like the Twitter fail whale).

And if you’re feeling inclined to make your own custom error or maintenance page, we have included some helpful advice at the bottom of this post (a “best practices” of sorts).

The fun (or very strange) ones

YouTube

YouTube is known for being one of the services that have truly charming error pages, in lots of varieties.

Update: It turns out that the above page is actually not an official YouTube error page but a satirical take done by Brendan McGetrick. It’s still a great example, though, so we’ll leave it in here.

Mixx

This one is brilliant. Not only do they entertain the user, they manage to do some branding in the process.

Twitter

Twitter’s most (in)famous error mascot is the Fail Whale, but their error pages show more diversity than that. This is another (quite trippy) example.

Yahoo Mail

We like the touch with “rest assured the alarms are blaring in the basement.”

Flickr

This has to be one of the most original error pages we have seen. Flickr turned it into a competition! Talk about distracting the user in a smart way.

Orkut

While not visually exciting, the error message is a classic.

Myspace

During one of its biggest service outages ever, MySpace did a brilliant thing: they put up a page with a playable Pacman game to keep people entertained.

Stumbleupon

We don’t want to go outside… It’s RAINING. (We’re in Sweden.)

Reddit

When all else fails, blame the Large Hadron Collider.

Ning

Showing pictures of your tech staff is always a great idea. Especially if they are fluffy animals.

The to-the-point ones

Typepad

The error page is simple and to the point, but what is brilliant here is the second page below. It’s not an error page, but was set up after Typepad had experienced problems, letting users choose their own compensation. We wonder which option turned out to be the most popular? (If anyone from Six Apart is reading this, care to share that information with us?)

Hulu

Hulu has clearly opted for keeping things simple.

Linkedin

Linkedin always brightens up their maintenance pages with their magician/gnome/elf (what IS that?), yet the message is professional and to the point.

Facebook

Another example of keeping things really simple. Perhaps a bit too simple.

Amazon

When money is involved, it might be best to avoid jokes.

Wikipedia

Wikipedia takes a very international approach… “Error” in 10+ languages.

Digg

This is another classic error/maintenance page. Tipping the visitors about other cool sites in the meantime is a pretty neat thing.

Blogger

Google’s Blogger service has a simple and to-the-point error message.

Netflix

Paying services may do well to stay away from jokes. Here is a nice example from Netflix (another one from Amazon above).

Mozilla

Polite and to the point, and visually pleasing.

Technorati

We didn’t include the famous “oops, the technorati monster escaped” error message, but instead this maintenance page.

Sourceforge

Note the link to a status page. Always a good practice.

The non-existent ones

Microsoft Technet

Ok, this one can’t really be considered a Web 2.0 service, but we included it because this example shows more or less the worst case scenario. There simply is no custom error page present here at all.

Google

Google’s error pages are infamous for being uninformative. At least they have put their logo in there, but that’s about it. “Service error -27″? Ok…

Some advice about maintenance and error pages

The examples in this post are just a small sampling of the creativity (or in the last examples, lack of creativity) that companies have shown when setting up their maintenance and error pages. We hope you found them inspiring!

Counting on getting errors may seem a strange and counter-intuitive thing to do, but you might as well have a maintenance page ready for when you might need it, not to mention having a custom error page if your website suffers from an unexpected error.

Here are a few points that you might want to keep in mind when designing error and maintenance pages. Many of these may seem obvious, but if you’ve been around the Web for a while, you will have seen plenty of cases where this advice would have been needed.

• Keep an appropriate tone. Keep the tone in line with the service you provide. If you’re all about entertainment, entertain. If not, then maybe it might be a good idea to leave out the jokes.
• Be polite. You have just inconvenienced the visitor. Don’t make it worse.
• Don’t blame the user. Really. We have seen error pages that firmly state that the user did something wrong.
• Be informative. Let the user know what is going on and that you are doing something about it. If you know when the site will be back, let the user know.
• Provide up-to-date information. If you have a status page, link to it.
• Brand the page. It may be a simple error page, but at least include your logo so there is no doubt to the user what website he/she is on.

The advice above overlaps with a very specific kind of error page we have written about before, the 404 error page (page not found). You may want to check out these two posts for further inspiration:

Facebook has announced that it now has 400 million active users. Just one year ago Facebook had 150 million users, so 2009 was an incredible year for the social media giant.

There can be no doubt that Facebook is pretty much unstoppable at the moment, a real juggernaut. For some perspective on Facebook’s amazing growth, we have put together this infographic. We hope you’ll enjoy it!

Sometimes you want an easy way to share your Pingdom monitoring data with others. So far we’ve had public report pages that you can use, but now we’ve added one more sharing method that is very flexible and easy to use.

Unless you’ve been hiding under a rock lately, you’ll know that last week Apple announced the iPad, its new tablet device. Reactions have been a mixed bag, and a storm of discussion has swept through the blogosphere about various features the iPad should or shouldn’t have had.

One of the main complaints so far has been the iPad’s lack of multitasking. (To be precise, multitasking is a bit of a misnomer here; the iPhone OS has multitasking. What people really mean is only allowing one app at a time to run.)

The tech industry is littered with billionaires. We all enjoy a good income, but some clearly have earned more than others. Much, much more. The question is, how much money do the really big names in tech actually have?

To find out, we went through the Forbes 400, a list of the wealthiest Americans, and filtered out the people who work within the tech field, or more specifically: IT.

So here they are, the 20 richest Americans in tech today.
