YouTube is available in Ethiopia as of 2015, according to the tech site Digital Inspiration. While individual videos may be blocked, the site itself is rarely blocked except in certain countries.
Ethiopia is not among the countries with a history of censoring YouTube. In the past, such countries have included Turkey, Pakistan, Russia, Bangladesh and the United Arab Emirates. In China, Iran and North Korea, YouTube remains blocked as of April 2015.
Though use of YouTube itself is not restricted in Ethiopia, it is possible for content owners to restrict their content to certain countries. As such, certain specific videos are not available on YouTube when accessed from Ethiopia, though the site itself remains unblocked.
