Twitter said Thursday some users could not access the messaging service amid reports of an outage in some parts of the world.
“We are currently investigating issues people are having accessing Twitter,” a spokesperson said in an email. “We’ll keep you updated on what’s happening.”
The monitoring website DownDetector showed a series of outage reports starting at 1846 GMT, concentrated in Europe, North America and Japan.
Users trying to access Twitter saw a message saying “Something is technically wrong.”
The outage occurred as President Donald Trump convened what he called a “social media summit” where conservative critics of Silicon Valley were expected to voice grievances.
Trump, who has more than 60 million followers on Twitter and uses the platform extensively, nonetheless has complained that it suppresses some political viewpoints.
Earlier this month Facebook experienced an outage of several hours due to what the company said was a bug triggered by a maintenance operation.
‘How dare you?’ Greta Thunberg berates world leaders at UN
A visibly angry Greta Thunberg berated world leaders as she addressed a UN climate summit on Monday, accusing them of betraying her generation by failing to tackle greenhouse gas emissions and asking "How dare you?"
The Swedish teen, who has become the global face of the growing youth movement against climate inaction, began by telling her audience: "My message is that we'll be watching you," eliciting laughter.
But it was soon clear that the tone of the message would be very serious.
‘The transcript has to come out’: Fox News pundit unloads on Trump over his Ukraine scandal
A Fox News pundit on Monday said the Trump administration had no choice but to release a transcript of a controversial call with Ukraine's president, in which Trump allegedly pressured the foreign country to investigate his potential Democratic rival Joe Biden.
Trump has insisted that the call with Ukraine's Volodymyr Zelenskiy was "largely congratulatory" and focused on corruption. But the Trump administration attempted to block a whistleblower complaint about the conversation.
"Look, the administration made a serious error in excessive secrecy. If it is what the president says it is, then the effort to conceal it makes it worse, right?" said Fox News political editor Chris Stirewalt.
Explosive report shows how foreign entities are bombarding US servicemembers with pro-Trump propaganda
Social media sites like Facebook and Twitter played a critical role in helping Russia-affiliated trolls disseminate propaganda to divide and manipulate voters in the 2016 presidential election.
But it hasn't stopped. A new report from the Vietnam Veterans Association has uncovered an ongoing two-year effort by actors in several foreign countries, including Russia, to target U.S. veterans and servicemembers.
The report shows that "These foreign admins have created individual social-media accounts that purport to belong to American veterans working at reputable veterans organizations," and use the accounts both to "send friend requests to the relatively small community of veteran advocates and connect with its prominent members who work to shape federal policy" and "spread propaganda and false news, while shaping and moderating/censoring the conversations of the unsuspecting community of American veterans who follow or join these groups and pages."
