Half the internet goes down as Cloudflare blames issues on 'fiber cut'

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.
