Meteors will fall into the target-site and cause huge explosions,
destroying big areas around ground zero. This is how dinosaurs disappeared;
no reason why a website should resist!
Soft destruction for the target-site, being slowly drowned by waters.
No options for this catastrophe.
Mother Nature always wins in the end. So why not grow flowers on those world wide grounds?
Of course, you might think that it doesn't look much like a disaster. But if you let these flowers grow on the homepage of a death-metal-gothic-suicidal-hard-rock band, or on the site of your country's Department of Defense, you'll find out that it definitely is a disaster.
