Multiple outages hit social media, government and news websites across the globe including New York Times, Financial Times, and CNN on Tuesday, with some reports pointing to a glitch at US-based cloud computing services provider Fastly.
Dozens of high-traffic websites including the New York Times, CNN, Twitch and the UK government's home page were down. Agencies could not immediately confirm the issue affecting the sites.
San Francisco-based Fastly acknowledged a problem just before 1000 GMT. It said in repeated updates on its website that it was “continuing to investigate the issue."
Most of Fastly's coverage areas were facing "Degraded Performance", the website showed.
Visitors trying to access CNN.com got a message that said: "Fastly error: unknown domain: cnn.com."
Down Detector, which tracks internet outages, said: "Reports indicate there may be a widespread outage at Fastly, which may be impacting your service."
Separately, Amazon.com Inc's (AMZN.O) retail website also seemed to be down.
Nearly 21,000 Reddit users reported issues with the social media platform, while more than 2,000 users reported problems with Amazon, according to outage monitoring website Downdetector.com.
Amazon's Twitch was also experiencing an outage, according to Downdetector's website.
Websites operated by news outlets including the the Guardian, and Bloomberg News also faced outages.
