Fastly's CDN Reportedly to Blame for Global Internet Outage
A huge outage has brought down a number of major websites around the world. Among those affected are gov.uk, Hulu, PayPal, Vimeo, and news outlets such as CNN, The Guardian, The New York Times, BBC, and Financial Times.
It is thought a glitch at Fastly ─ a popular CDN provider ─ is causing the worldwide issue. Fastly has confirmed it’s facing an outage on its status website but fails to specify a reason for the fault ─ only that the problem isn’t limited to a single data centre and, instead, is a “global CDN disruption” that is potentially affecting the company’s global network.
“We’re currently investigating potential impact to performance with our CDN services,” the firm said.
What is Fastly?
Fastly is a content delivery network (CDN) company that helps users view digital content more quickly. The company also provides security, video delivery, and so-called edge computing services. They use strategically distributed, highly performant POPs to help move data and applications closer to users and deliver up-to-date content quickly.
The firm has been proving increasingly popular among leading media websites. After going public on the New York Stock Exchange in 2019, shares rose exponentially in price, but after today’s outages, Fastly’s value has taken a sharp 5.21% fall and are currently trading at US$48.06.
What are CDNs?
Content delivery networks (CDNs) are a web of small computers, or servers, that link together to collaborate as a single computer. CDNs improve the performance of internet-connected devices by placing these servers as close as possible to the people using those devices in different locations, creating hundreds of points of presence, otherwise known as POPs.
They help minimise delays in loading web page content by reducing the physical distance between the server and the user. This helps users around the world view the same high-quality content without slow loading times.
Without a CDN, content origin servers must respond to every single end-user request. This results in significant traffic to the origin and subsequent load, thereby increasing the chances for origin failure if the traffic spikes are exceedingly high or if the load is persistent.
The Risk of CDNs
Over time, developers have attempted to protect users from the dangers of overreliance through the implementation of load balancing, DDoS (Denial of Service) protection, web application firewalls, and a myriad of other security features.
Clearly, by the state of today’s major website outage, these measures aren’t enough. Evidently, CDNs present a risk factor that is widely underestimated ─ which needs to be rectified with haste. Content delivery networks have become a key part of the global infrastructure, and so it’s imperative that organisations start to figure out risk mitigation strategies to protect companies reliant on the interconnected service from further disruption and disarray.
Webinar: OT networks, ransom attacks, and cyber resilience
Operational Technologies (OT) infrastructures across industrial sectors such as manufacturing, transportation, utilities, and oil & gas are increasingly becoming the target of sophisticated cyberattacks.
In recent months, cyberattacks have been making headlines, focusing executive attention on cyber resiliency and how organisations can take the right steps to keep themselves safe.
In the past, many OT infrastructures were self-contained and isolated (or "air-gapped") from corporate resources, so they were relatively safe from internet-based threats. Not so much today. As OT and IT networks converge, outdated and unpatched OT endpoints represent a tempting entry point for cyber attackers.
Preparing for, responding to, and recovering from cyberattacks should be a strategic part of your business continuity plan.
BizClik Media Group and Fortinet invite you to our live webinar, taking place on 24 June 4 pm BST. The event, entitled ‘When, Not If: Responding when your OT network suffers a ransomware attack’, will allow people who are joining live to ask questions.
What will the webinar cover?
- Trends impacting the multiple attack points across the industrial threat landscape
- Insights garnered from purpose-built threat intelligence and supporting services for developing cyber resilience
- A platform approach for broad, automated and integrated cyber resilience
