Dropbox uses Amazon S3, therefore servers are located in Europe as well.

EDIT: maybe my statement was a bit premature. I was confident Amazon was keeping mirrors, but it seems they only do this in the same region. Dropbox runs its own infrastructure network and uses AWS for storing files, both solely in the US.

They don't use S3 now. That was way long ago.

Sync a file via Dropbox and run lsof -i, and you get something like this: ec2-54-221-232-10.compute-1.amazonaws.com:https

EDIT: it may be that they use EC2 for their infrastructure, but not for actually storing files. But they still use AWS.

That doesn't follow in the slightest. Just because AWS has data centres around the world, it doesn't follow that Dropbox is using them.

Do you have any sort of cite for your claim? Because the link in the comment you're replying to suggests that they store everything purely in the US.

Dropbox transfers everything to the USA even if you are in Europe (I checked that with Wiresharks and traceroute). Because of that my main issue with Dropbox was always speed: Uploads and downloads were almost never higher than 500-700 kB/s even though my connection can do much more.

Do they use the European servers? It would be a lot more expensive from their point of view.
