The US Department of Defense has announced the appointment of Dana Deasy, the former Chief Information Officer of JPMorgan, as its own CIO.

“I'm pleased to announce that Mr Dana Deasy will serve as the Department of Defense chief information officer. He is joining us from JP Morgan,” said Dana White, the Pentagon’s Chief Spokesperson.

In his new role, Deasy will become responsible for the management and use of information, communications and cybersecurity for the Department of Defense.

His appointment comes at a time when the Pentagon is looking more readily to enhance its IT networks with technologies such as the cloud, having opened bidding for a multibillion dollar cloud services contract that Amazon is expected to obtain, despite competition from Oracle, Microsoft, IBM and others.

“Mr Deasy's extensive enterprise-level experience and leadership will ensure the department drives a culture of performance and maximizes the value of every taxpayer dollar entrusted to us,” White continued.

Having stepped down from his role at JPMorgan in September, Deasy will now join the Pentagon in early May.

Upon his enrolment, Deasy will replace Essye Miller in the position who has been filling in on an interim basis since John Zangardi stepped down from the post after becoming CIO of Department of Homeland Security.

Fastly's CDN Reportedly to Blame for Global Internet Outage

Multiple outages have hit social media, government, and news websites across the globe

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. 

Over the coming days, both Technology Magazine and Data Centre Magazine will continue to provide updates on the current situation as developments are made.
