On Wednesday, thousands of Twitter users were unable to access the social media platform and reported the outage to the Downdetector outage monitoring website.
Downdetector monitors outages by compiling status reports from various sources, including user-submitted errors on its platform.
According to our correspondent's checks on Wednesday at 11 a.m., 3,473 Twitter users had already reported the outages on Downdetector.
The outage appears to be primarily affecting the app, though some users have also reported problems with the website.
The unexplained collapse comes on the heels of Elon Musk's latest round of layoffs, in which he fired around 200 product managers, data scientists, and engineers in charge of site reliability.
