Simply beautiful:

Not a pretty sight
When the web dies screaming loud
The site is not found.

Morning and sorrow
404 not with us now
Lost to paradise.

The dream is shattered
The web site cannot be found
Inside the spring rain.

Click exciting link
Gossamer threads hold you back
404 not found.

Aborted effort:
The site, passed this veil of tears.
You ask way too much.

Site slips through fingers
Pulse pounding hard and frantic
Vanishing like mist.

The web site you seek
Lies beyond our perception
But others await.

Emptyness of soul
Forever aching blackness:
"Blah.com not found."

Rather than a beep
Or a rude error message,
These words: 'Site not found.'

Something you entered
Transcended parameters.
The site is unknown.

Won't you please observe
A brief moment of silence
For the dead server?

Cables have been cut
Southwest of Northeast somewhere
We are not amused.

Site is silent, yes
No voices can be heard now
The cows roll their eyes.

To have no errors
Would be life without meaning
No struggle, no joy

Errors have occurred.
We won't tell you where or why.
Lazy programmers.

Server's poor response
Not quick enough for browser.
Timed out, plum blossom.

Login incorrect.
Only perfect spellers may
Enter the system.

The code was willing
It considered your request,
But the chips were weak.

Something's gone awry.
Click the grey "OK" button.
Your only choice now.
