In a recent post, we talked about the ten strangest data centre outages. Modern data centres are very secure, but there are a handful of examples (like a squirrel taking out a Yahoo! data centre by chewing through cable) of strange outages that sound too strange to be true.
But sometimes, this sort of unique situation isn't just limited to what happens inside of a data centre. As we've found, sometimes, it's the data centre itself that's strange.
Up until 2008, HavenCo maintained a data centre on the tiny Principality of Sealand, which is essentially a WW2 anti-aircraft platform seven miles from the English coast that sits in international waters (though most countries don't recognise it as a sovereign nation). The first offshore data centre, it could host content deemed illegal in other countries.
The Citi Data Centre in Frankfurt, Germany, has a roof that's made up of 72% green vegetation, uses fresh air to cool its servers 65% of the year, and is expected to save 50 million liters of water a year via reverse osmosis water treatment to reduce sediment in its cooling towers. Needless to say, it's a pretty green data centre.
Bahnof hosts a data centre in Sweden that is nuke-proof. Resting in a mountain beneath 100 feet of rock, it's sealed off with 16-inch thick doors. The centre is so secure it has hosted a few of Wikileaks's servers.
The Barcelona Supercomputer Centre is located in a former Christian chapel in Spain. What looks like a regular chapel from outside houses Europe's eighth most powerful supercomputer.
The look and physical layout of the average data centre is rapidly evolving these days as companies experiment with unorthodox locations and innovative data centre designs. So who knows? Perhaps the world's strangest data centres might look even stranger in a few years.
