Twitter is suffering an outage as users around the world say they’re unable to log into the social media website for the second time in hours.

The social media giant’s dashboard said “all systems operational” as of 5.30pm UK time on Saturday, about an hour after Twitter Support wrote: “We know that parts of Twitter still aren’t working for some of you.

“We’re fixing an issue with our servers to get things back to normal soon. Thanks for sticking with us.”

Twitter’s API status website said its data team was investigating “a possible system irregularity”

Twitter also reported problems on Friday night as users in Europe, the US and parts of Asia, Africa and South America were unable to log in or send tweets.

The company tweeted at the time that users may not be able to access the site and that it was “working on fixing a problem.”

Problems resurfaced or continued on Saturday afternoon, as users in the UK and other countries said they were unable to log in or post tweets.

There was a surge in user reports of Twitter being ‘down’ late on Friday night, or in the early hours of Saturday morning in Britain, according to the website Downdetector.

There were smaller spikes at about 1pm and 4pm on Saturday, with bigger spikes countries such as Mexico, Japan, the Philippines, Singapore, New Zealand and South Africa.

Following Friday night’s outage, Twitter Support wrote: “Tweets may not be loading for some of you. We’re working on fixing a problem and you’ll be back on the timeline soon.”

Around 40,000 Twitter users reported issues with the social media site between 12.48am and 2.03am UK time, according to the outage monitoring website Downdetector.

The website had also published a ‘Twitter outage map’ which shows issues have been reported by people across Europe and in the US.

Users in Mexico, South America, South Africa and the Philippines are also having problems with the site, according to the map.

One user wrote: “If I may, I will add to the list of current issues: not being able to tweet, retrieve, load tweets, bookmarks, or even log in now. It was working perfectly earlier today.”

Another wrote: “Some people can’t log back onto the twitter app either, it keeps saying error.”

Millions were unable to send tweets for over two hours when the website crashed in October 2020.

The company said it was caused by an “inadvertent change” to Twitter’s internal systems and the website was not hacked.
