Multiple outages hit social media, government and news websites across the globe on Tuesday morning (June 8), with reports indicating a glitch at US-based cloud computing services provider Fastly.
Fastly said it was investigating “the potential impact to performance with our CDN [content delivery network] services”, according to its website. Most of Fastly’s coverage areas were facing ‘Degraded Performance’, the website said.
Separately, Amazon.com Inc’s retail website also seemed to be down. Amazon was not immediately available to comment. 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 Financial Times, The Guardian, The New York Times and Bloomberg News also faced outages.
Qatar-based Al Jazeera Media Network was also affected. France’s Le Monde newspaper started showing error messages that appeared on the website at around 10 GMT.
The UK government’s main website too was unavailable. The White House website had an error message but was later available.
Messages such as “Error 503 Service Unavailable” and “connection failure” appeared.
Visitors trying to access CNN.com got a message saying: “Fastly error: unknown domain: cnn.com.”
The Guardian technology editor, Alex Hern, said in a Twitter thread serving as the website’s ‘formal liveblog’: “The increasing centralisation of internet infrastructure in the hands of a few large companies means that single points of failure can result in sweeping outages.”
He said Fastly “has been identified as the cause of the problem”.
The official GOV.UK Twitter account said: “We are aware of the issues, which means that users may not be able to access the site. This is a wider issue affecting a number of other non-government sites. We are investigating this as a matter of urgency.”
Fastly wrote on its website: ‘This incident affects: Europe (Amsterdam (AMS), Dublin (DUB), Frankfurt (FRA), Frankfurt (HHN), London (LCY)), North America (Ashburn (BWI), Ashburn (DCA), Ashburn (IAD), Ashburn (WDC), Atlanta (FTY), Atlanta (PDK), Boston (BOS), Chicago (ORD), Dallas (DAL), Los Angeles (LAX)), and Asia/Pacific (Hong Kong (HKG), Tokyo (HND), Tokyo (TYO), Singapore (QPG)).’
What is 503 Error?
It is a computer’s way of saying the online destination you want to visit isn’t available at the moment. All websites and services are hosted on computers called servers. These are what your web browser connects you to when you type in an address.
The 503 error occurs when that connection is blocked, either because the server is down for maintenance or because there’s an unscheduled error.
It can also be that the server has simply been overloaded with too much traffic. In some cases, the error may be fixed on your side by refreshing the page or restarting the computer. But, if it’s a larger problem, then you will need to wait for the host server to reassert.
It is a cloud computing company that offers, among other things, a content delivery network (CDN) for other companies to use.
The company runs what is called ‘edge cloud’, which speeds up loading times for sites and protects them from denial-of-service attacks, as well as helping them deal with bursts of traffic.
But that means Fastly has to be an intermediary between its clients and their users. So, if the service as a whole suffers an outage, it can prevent all the clients from displaying their sites to users. That is why so many companies are affected by the problem.
