Twitter crashed early Wednesday, just days after owner Elon Musk axed hundreds of staff and soon after a cryptic threat from China.
Users were able to get to the “Welcome to Twitter!” welcome page, but without their news feeds showing up.
Individual feeds were still accessible, but seemingly with no fresh content. And while it appears possible to send fresh tweets, they do not show up on other users’ unaccessible timelines.
Reports started coming in of issues just before 4:50 a.m. — with more than 4,000 by just after 5:30 a.m., according to Down Detector.
More than half of those complaints came from people unable to access the site by app.

It was not immediately clear what caused the crash, with Chief Twit Musk presumably unable to use his own $44 billion site to share updates.

It comes just days after the once-again world’s richest man laid off another 200 staffers — bringing the site’s workforce down to under 2,000, a dramatic decrease from the 7,500 there when he took over last year.
Musk also got a cryptic warning from China’s state-run Global Times newspaper not to share theories about the origins of COVID, which the FBI and US Department of Energy now confirms is most likely a Wuhan lab leak.
Before the crash, Musk was up until at least 2 a.m. in Austin, Texas, testing a new microphone feature for chats on Twitter Spaces, cackling as he distorted his voice — and made bathroom noises and even loud farts.
His last official tweet was a high-brow joke at 1:25 a.m.
“What do you call an infinite gear ratio? All torque, no action.” he wrote.
