At CeBIT 2009 it today was announced that SharePoint Online is now available worldwide*. SharePoint online is a part of the Business Productivity Online Suite which also contains Exchange Online and Live Meeting. More services will be available at a later date.
There is a free 30 days trial option if you would like to try it out, which I really recommend, before you subscribe/buy the solution.
* These are the possible countries: Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, the United Kingdom and the United States
