This morning, there was a significant outage for the social network Twitter that lasted for around 40 minutes. Around 8:05 AM ET, problems with the service began to surface. Many users reported receiving “over capacity” and even “this website is down” error messages. The problems impacted Twitter on the web, on mobile devices, and even in the TweetDeck app.

Thousands of Twitter problems were reported by Downdetector, yet Twitter’s own status page said that “all systems functioning.” Many users were unable to log in or read tweets even when the main Twitter.com URL loaded. Around 8:40AM ET, Twitter began to come back to life, and many users were able to tweet and access the service once again.

We’re trying to get it back up and running for everyone, Twitter stated at 9:10 AM ET. The majority of users seemed to be re-connecting as of 12:37 PM ET, and Twitter has announced a complete resolution, blaming an unidentified issue with internal systems.

This is the first significant outage on Twitter since the social network began experiencing issues in February. In February, Twitter went offline twice in a single week, rendering users in some US regions unable to use the site owing to a “technical problem that was blocking timelines from loading and Tweets from publishing.”

These most recent Twitter service troubles occur only days after the social media platform sued the richest man in the world, Elon Musk. On the grounds that Twitter has not complied with requests for information on bot and spam behavior on the site, Musk is attempting to back out of a $44 billion takeover offer.
