Some Twitter users were having trouble with the social media service Friday morning, as the company noted, and service distruptions continued through the afternoon.
"Some users are currently experiencing problems accessing Twitter & Tweeting. We are aware of the issue and are working towards a resolution," the Twitter Support account said in the morning.
The Twitter service tracker noted a disruption in the timeline function, and more performance issues with the stream. Those reports were in effect for hours.
The website-tracking site DownDetector noted spikes in outage reports after midnight, 9 a.m. and 1 p.m. ET. The U.S., U.K., France and Japan appeared especially hard-hit.
