Twitter appears to be down for some users in France, with at least some blaming ad-blocking software.
Twitter users started reporting an outage on Downdetector Sunday, primarily when accessing Twitter via a desktop web browser. Phone and tablet apps appeared to work just fine.
Interestingly, according to some users, turning off ad-blocking software in their web browser fixed the problem. So far, Twitter has not issued a statement or acknowledgement.
It remains to be seen if the issue was the result of an error, or if Twitter is beginning to target ad-blocking software.
