A really high amount of sites like Reddit, Spotify, Twitch, Stack Overflow, GitHub, gov.uk, Hulu, HBO Max, Quora, PayPal, Vimeo, Shopify, Stripe, and news outlets CNN, The Guardian, The New York Times, BBC and Financial Times are currently facing a downtime. It is most likely because a really popular CDN Network has gone down.

A key component of the cloud computing is the Content Delivery Network (CDN). These companies operate global server networks to improve web service performance and accessibility. CDNs act as proxy servers and cache certain data as close as possible to the end user. For example, media content on a near-by CDN Server is often cached so that every time a user loads a web page it does not have to be fetched on the original server.
CDNs have begun over time adding additional features, including load balancing, DDoS protection, Web application firewalls and various security features. Fastly, Cloudflare, Amazon Web Services CloudFront and Akamai include popular CDNs.

A CDN, or content delivery network, is a system of servers that deliver web pages to your browser. These servers are strategically placed throughout the world to deliver content faster and more reliably than traditional hosting services. What does this mean for you? It means less time waiting on websites and a better experience! To learn about how CDNs work, keep reading!
How do CDNs work?
A CDN is a network of servers that are placed all over the world to deliver content faster and more reliably. When you click on a web page, your browser requests it from one of these strategically located servers. The closer the server, the less time it takes for your request to be fulfilled – which means less waiting!
CDNs can also help ensure that traffic spikes don’t overload websites because they have enough capacity in place to handle high volumes of traffic. It’s not unusual for users on popular sites like Facebook or YouTube to experience slow performance during peak periods as their visitor numbers swell tens-of-thousands at a time – but this doesn’t always happen thanks to CDNs doing what they do best: delivering data faster.
Benefits of a CDN?
– Faster loading times
– Better website performance
– More reliable site availability
CDN Providers:Akamai, Cloudflare, Edgecast Networks Inc., Level(X), Limelight Networks. What are some of the CDNs that you can use?
If you’re in need of a CDN provider for your business or organization and have considered using Akamai, Cloudflare, Level(X) or Limelight – I’d recommend giving them all consideration because they each offer different features to fit every project’s needs. They also offer API access which is great if you want to take control over the cache expiry time on your own content!
CDN reliability and redundancy
It is a huge factor when choosing the right CDN provider for your business or organization, and these three providers are ranked among the most reliable.
– Akamai: handles over 200 trillion internet interactions each day; 99.999% uptime SLA (service level agreement)
– Cloudflare: handles 50 billion requests per day; has an extremely high reliability rate of 100% – 500 ms downtime per year with a typical average of less than 40 milliseconds
– Level(X): offers global coverage across 18 points of presence in North America, Europe and Asia Pacific regions and has more than 90+ data centers in 44 countries worldwide including locations such as Sydney Australia, Dubai UAE & Hong Kong China.
Fastly is famous amongst the news sites in general.
What are the security risks to a CDN?
– If the CDN goes down, then it can cause your site to go offline
– You must make sure that you are using a trusted service provider. The default settings for many providers may not be best suited for your website or blog and if anything happens to disrupt their servers (such as an outage), there is nothing stopping them from taking your files with them! It’s important to research what type of security measures they have in place and how often backups are taken.
How much do these services usually cost?
– Akamai: starts at $25 per Mbps/month – 100Mbps minimum bandwidth required; Cloudflare: starts at $20 per month – no bandwidth requirements; Level(X) pricing varies by region
What should I do if my CDN goes down?
– You will want to contact the provider ASAP and find out what may have caused the outage.
– If you are using Akamai, they offer CloudWatch monitoring that can alert you of any issues with your service on a real time basis.
I’m not sure which one is best for me… What else should I look at?
– Make sure that whichever provider you choose has data centers in all or most regions where people might be viewing your site from (Akamai offers over 1000+ worldwide) – this way there’s less chance of an issue happening because someone is trying to access information from a different location than their own.
– With Akamai, you can make sure that your site is using the fastest possible connection to a particular country based on latency by specifying DNS nameservers for each region in their Cloud Control Panel.
