Doesn't work for me in the Netherlands. Down since this morning. Though I used Tor and could access it via an IP in Ghana. I have new emails so I am pretty sure they keep arriving.
I share the positive sentiment about Fastmail here. Using it close to 10 years without issues. The times I needed there support for some more complex configuration question and they replied thoroughly and quickly. I normally dislike web interfaces but their UI is really well done.
