The internet has been hit with another major outage after Cloudflare suffered an error.Websites including Transport for London, LinkedIn, Zoom and the outage monitor Downdetector were all unusable on Friday morning.

A huge internet outage took place last month due to service provider Cloudflare. Now, a variety of websites were knocked offline once again.

This latest event follows hot on the heels of Nov. 18, when Cloudflare was hit by a global outage for several hours.

Shares of the company were down 4.5% in premarket trading after global websites went down and Cloudflare said it was investigating.
