Some of the issues appear to have now been resolved.
A major outage affected a number of leading websites around the world on Tuesday.
Websites of media outlets including BBC, New York Times, CNN and the Guardian were all affected, while many others including Amazon, Reddit and Spotify also went down in the outage.
Service monitoring website Down Detector also showed a spike in reports of outages around the world.
It was understood the outages could be related to a problem at content delivery network (CDN) provider Fastly.
The company offers services such as speeding up loading times for websites, protect them from denial-of-service cyberattacks and helping them deal with bursts of traffic in order to stay online and stable.
Fastly offers a variety of services such as shortening loading times for websites, protection from cyberattacks and helping websites deal with high volumes of traffic.
“We’re currently investigating potential impact to performance with our CDN services,” the firm said.
In a tweet, the Guardian said: “The Guardian’s website and app are currently being affected by a wider internet outage and will be back as soon as possible."
At the time of writing, a number of the websites appear to be operational again while some others remain unavailable.
