Twitter users around the world reported that they could no longer post messages or send messages to one another on Wednesday, the latest in a series of glitches at the social media service owned by Elon Musk.
The problems began around 4:45 p.m. Eastern time on Wednesday, when users who tried posting messages saw a notification that said they were “over the daily limit for sending tweets.” Others found they were unable to follow new accounts, and some were logged out of their accounts altogether. Direct messages and the search function for GIFs also stopped working.
Downdetector, a service that collects user reports of outages, also said Twitter was experiencing problems.
The cause of the glitches was unclear. Twitter and Mr. Musk did not immediately respond to requests for comment.
Twitter has undergone significant changes since Mr. Musk bought the company in October. The billionaire has laid off or fired more than half of Twitter’s staff, leaving the company with about 2,200 employees, down from 7,500 at the time of the acquisition. Mr. Musk has also aggressively cut other costs and proposed new ways for the company to earn revenue.
The changes have led to confusion and occasional breakdowns in its service. Twitter users experienced outages in late December, after the company shuttered operations at one of its main data centers in Sacramento. That outage, which lasted several hours, primarily affected people who used the application on desktop computers, logging them out or surfacing error messages when they tried to scroll their Twitter feeds.
Last month, users in Australia and New Zealand also reported Twitter outages that lasted more than half a day.
