Countless popular websites, including Reddit, Spotify, Twitch, Stack Overflow, GitHub, gov.uk, Hulu, HBO Max, Quora, PayPal, Vimeo, Shopify, Stripe, as well as media CNN, The Guardian, The New York Times, BBC and the Financial Times is facing interruption.

According to a product manager in the Financial Times, it is believed to be a flaw in the popular CDN provider, Fastly. Fastly has confirmed that its status website is facing outage.

“We are currently investigating the potential impact of our CDN service on performance,” the company said.

Update at 3:50 AM PT: Some websites are slowly recovering. “The problem has been identified and a fix is ​​being implemented,” San Francisco-based Fastly said on its status page.

Update at 4:02 AM PT: The problem seems to have been resolved, and the affected websites and services can now load normally. The company has not communicated the reasons for the interruption.

Generally speaking, it lasted about an hour. The content delivery network (CDN) is a key part of the Internet infrastructure. These companies operate a global server network to improve the performance and availability of Web services.

The CDN acts like a proxy server and caches some data as close as possible to the end-user. For example, media content is usually cached on a CDN server near you, so you don’t have to retrieve it back to the original server every time a user loads a web page.

Although the network is a digital platform, it is very physical in nature. When you load a page on a server on the other side of the world, it takes hundreds of milliseconds to get the page.

Over time, this delay will accumulate and it feels like a slow experience. When the page has been cached, the CDN can usually start serving the page content in less than 25 milliseconds.

Over time, CDNs have added more features, such as load balancing, DDoS protection, web application firewalls, and other security features.

Popular CDNs include Fastly, Cloudflare, CloudFront on Amazon Web Services, and Akamai. Especially Fastly is very popular among media websites. The company went public in 2019.

The stock price of Fastly (NYSE: FSLY) is currently trading at US$48.06, a 5.21% drop from yesterday’s closing price. He quickly referred to it as a “global CDN outage” and appeared to be affecting the company’s global network.

The latency rate is increasing for local traffic within the country. There is a great interval of time in stimulation and response. That is creating problems for the servers and customers. To reduce this effect the Internet Exchange Point (IXP) has been introduced in Pakistan. It is the first of its kind. This is like a bridge between two lands. This bridge links Internet Service Providers (ISPs) and Contact Delivery Networks (CDNs) to exchange network traffic.
Initially IXP is a connection which lets two networks to connect directly without any interference from other networks. This is one to one link, making it easier for all networks.

Days back before the arrival of Internet Exchange Point the networks from abroad were routed using different proxies. The proxies were even used for traffic within Pakistan. Local connections will be allowed which will lower the pings and feedback time for local connections. The Pakistan Telecommunication authority allowed the construction of IXP on Pakistan. With the association of Internet Society (ISOC) it was introduced first time in Pakistan. IXP is located in the grounds of Higher Education Commission (HEC).

According to the sources, This testing is no longer than two weeks. If it is successful in Pakistan than it will be formally established in the country.

Govt is intending to establish more Internet Exchange Point in Lahore and Karachi very soon. Being a vital part of Telecommunication Policy 2015, Internet Exchange Point has now been established.

The policy is as follows:
“Internet and other traffic will be exchanged within Pakistan using local peering or exchange points as far as it is possible to do so, recognizing that the use of international peering points in other countries imposes an unnecessary cost burden and a potential security risk” “PTA will take appropriate measures in consultation with stakeholders to encourage establishment of local peering and exchange points of IP traffic on legally established gateways in Pakistan”

How does the Internet Exchange Point work? Now you don’t need to search any foreign networks because when you use local ISP a ping is sent to hosting server, for instance on Transworld and then IXP is used to route traffic located outside Pakistan. After that it will be sent to our local IXP once it is established.

The distance matters a lot in these kinds of networks. The distance between client and the main server is shorter but still the latency rate is high it increases because local internet request has to cover huge distance. It has to travel all the way to the hosting Internet Exchange Point to be routed back to the local server resulting in low data transfer rates.

The introduction of IXP is a great benefit to all networks. It is an important advancement in field of technology. It will provide a better communication, full on customer satisfaction, efficient business and a lot more.
