Any digital service hosted by Microsoft is limited by the US laws regarding exportations, too. There are still a lot of countries under varying US restrictions like Iran, Cuba, Syria, Libya, Sudan, North Korea, Myanmar, Liberia, Iraq, Zimbabwe, Balkans, Cote D'Ivoire, China, Canada, Germany, India, Israel, Pakistan, Russia, Egypt, Malaysia, Hong Kong, Kuwait, Lebanon, Singapore, South Korea, United Arab Emirates, the United Kingdom, Afghanistan, Belarus, Cyprus, Eritrea, Sierra Leone, Vietnam, Haiti, Rwanda, Somalia, Sri Lanka, Sudan, Yemen, Venezuela, Democratic Republic of the Congo... (straight from the US Export Controls page)
For some, it's only restrictions on military material, but technological stuff tends to be frowned upon too (if I remember well, ammunition exportation laws covered encryption too...).
Of course, it isn't a good excuse for the awful overpriced service provided anywhere but the USA.
