The circumstances suggest that it's probably just a simple error and not sarcasm. Not everyone in the world really loves sarcasm so much. People who use it frequently are usually trying to mask a poor imagination and small vocabulary. So I prefer to believe it's just a simple mistake. No big deal.
Sure, living under an autocratic invasion and having your internet access tightened is very "fortunate".
Ah sorry, maybe I should clarify: the above is sarcasm.
