X (formerly Twitter) has crashed for thousands of users this afternoon.
According to Down Detector, the problems with Elon Musk's social media platform started at around 13:30 GMT and are affecting users globally.
So far, more than 10,000 problems have been logged in the UK, while more than 42,000 have been logged over in the US.
While the reason for the outage remains unclear, more than half (57 per cent) of reports have been about the X app.
Meanwhile, 20 per cent of problems relate to the feed or timeline, while 17 per cent say they're struggling with the website.
The Daily Mail tried to access X on the iOS app and received an error message reading 'Posts aren't loading right now'.
On the X website, tweets also aren't loading, while the error message reads: 'Something went wrong. Try reloading.'
While the reason for the outage remains unclear, it may be linked to scheduled maintenance by Cloudflare - the network upon which X runs.
With X down, many users have flocked to Meta's rival app, Threads, to discuss the outage.
'Is it just me or is X down again?' one user asked.
Another added: 'Seems my X (formerly Twitter) is down cos I can't load anything on my phone and on my computer...is someone experienceing the same?'
And one joked: 'When Twitter down this where I come.'
This isn't the first time X has crashed in recent months - although it remains unclear if the latest issues are related to Cloudflare.
The outage comes just two months after X crashed twice, following repeated Cloudflare blackouts.
On 5 December, Cloudflare experienced a massive outage, knocking dozens of major websites offline.
Among those affected were Zoom, Canva, Discord, LinkedIn, Deliveroo, Substack, Shopify, Coinbase and Vinted.
So far, more than 10,000 problems have been logged on DownDetector in the UK.
Over in the US, there have been more than 42,000 reports over the X outage.
On Reddit, one user posted: 'Here we go again, it's down!'
Someone replied: 'Business halted. Second time in a month. It's too much for service as crucial as this. Something needs to be done.'
While a third said: 'imagine how much money businesses are losing.'
It marked the second outage in less than a month for Cloudflare, which powers internet requests for millions of websites.
Shortly after, Cloudflare admitted in a blog post that its network began 'experiencing significant failures to deliver core network traffic'.
The Silicon Valley company is the foundation of an estimated fifth of all websites worldwide.
Richard Ford, chief technical officer at Integrity360, said Friday's episode underlines how much of the internet now depends on a handful of infrastructure providers.
'For businesses, today is a wake‑up call,' the expert said. 'Relying entirely on a single provider for critical infrastructure is a fragile strategy.'
'Today's disruption underscores something many of us in cybersecurity and tech have long warned about - as the internet has grown more complex, a handful of infrastructure providers end up holding unexpectedly large power over its functioning.'
'Cloudflare sits at the heart of that, providing CDN, proxying, routing, DNS and caching so that websites can stay fast, secure and resilient under load.'
'When a provider like this fails, whether due to internal error, configuration change or external attack, the ripple effects hit far more than just a few sites.'
'What feels like one outage to a user is actually a systemic failure affecting traffic flows across many unrelated organisations.'
