Same here. CoralCDN has been around for ages, I've used it to auto-mirror images and other static content from sites to reduce bandwidth consumption. Works really well.

IIRC, it was originally devised to fix sites melting down under traffic spikes generated by Slashdot browsing crowd.

That's what I used it for! Of course, I never published anything worth getting Slashdotted :)

And to grab US only content from the UK. Ironically, it's usually BBC content...

Neat trick!
