Dozens of popular websites crashed on Monday, leaving millions without access.
Issues began at 8.35am ET on Monday, affecting a range of services including X, Zoom, Google and Microsoft.
Cloudflare, which provides web security, speed, and routing services for millions of sites, said it is investigating a fiber cut in Eastern North America and believes it is unrelated to the rest of the outages experienced globally.
A company spokesperson told the Daily Mail: ‘Cloudflare is not currently experiencing a global outage.
The only issue we’re aware of is that Zayo, a network provider, is experiencing an outage on some of its network routes.
That may cause some sites using Zayo exclusively to be unreachable, whether they use Cloudflare or not. We are seeing evidence that Zayo’s network is recovering and expect and errors to be short-lived.
At this time, Cloudflare said: ‘Traffic engineering efforts have successfully mitigated the majority of congestion and packet drops.
‘Services are largely stable, with only minor residual impact remaining. A small number of intermittent errors may still be observed for services with origins in North America as we work to fully clear the remaining load.’

A fiber cut occurs when a fiber-optic cable that carries internet traffic is physically damaged, disrupting the flow of data across a network.
Engineers must locate the break, dispatch repair crews and splice the cable back together before normal service can be restored.
While traffic can often be rerouted through backup connections, major fiber cuts can still trigger widespread outages if critical network routes are affected.
As it investigates the disruption, Cloudflare also reported a separate technical issue affecting some customers.
The company said it is investigating an issue preventing users from deploying Managed Rules, a set of built-in security protections designed to help defend websites against cyberattacks and malicious traffic.
Downdetector, a site that monitors online outages, shows users reported widespread problems with Cloudflare’s dashboard, while others said they were experiencing API authorization failures.
Other users reported encountering a ‘404 Error’ message when trying to log in.
Cybersecurity experts have issued a warning amid the disruption, telling users to be aware of fake backup links or mirror pages.
Millions of users are unable to access their favorite websites Monday morning
Web3 Antivirus, a software company designed to protect financial assets, said on X: ‘When major services like X, Reddit, Discord, Zoom, Canva and others start having issues, users may get trapped via ‘alternative’ access points, status updates and temporary mirrors.
‘A fake backup link or mirror page can look helpful during an outage, but it may lead to phishing pages, fake login forms, wallet drainers or malicious downloads.’
