Twitter users have been unable to post Tweets to their profile after being told they had reached their "daily limit".
The social media platform previously allowed users to post up to 2,400 tweets a day. However, reports of a glitch began at around 10pm last night, according to site Downdetector.co.uk.
Since then, the outage-website have received over 10,000 complaints, with the majority experiencing issues with the site's app rather than on PCs or laptops.
