Reports say Telegram was inaccessible for users in Europe, the Middle East, and North Africa.

Telegram spokesperson said “Some of our users in Europe and the MENA region are currently experiencing connection issues,” adding that “Please hang on, we have all hands on deck to bring you back soon!”

Telegram Messenger’s account on Twitter said in a post that “Europe is back online! Sorry to have kept you waiting. If you’re in Iran hang on just a little longer, back soon too.”

Iranian people account for nearly 40 million users of Telegram in the world.
