Geographical distribution of mining power/work Is there any information on how the mining power is distributed geographically? I.e. where the computers are located that do the work.

This is important as one measure of centralization of the system, and thus of the trust in the proof-of-work concept.

Of course, there are many different ways to measure centralization, but that's not part of this question.

Thank you!

PS: I'm open to suggestions for better tags of this question.
Not that I can find. You could work out the geographic distribution of mining pools based on information provided by blockchain.info, but they receive mining power from pool contributors from around the world, so that wouldn't really give you a complete picture. If a major pool went down (or was blocked off from the rest of the internet) most miners would just switch to another pool.
