Internet could be brought to knees easily. If it is arguable, just give a thought what had happened on Friday to the internet’s infrastructure in the United States. Epic cyberattacks crippled it disrupting availability of many popular websites including Twitter, Reddit, Netflix and PayPal.

According to the hacker group who had taken credit for the misconduct, it was just a dry run and a much bigger is on target.

The server infrastructure of Dyn Inc. was hit by distributed denial-of-service, or in the other and common words it was a DDoS attacks.

Dyn is a Manchester, New Hampshire-based company who manages internet’s infrastructure. In the DDoS attacks the machines are targeted with junk data traffic and this results with temporarily blocking of some access to websites.

CloudHarmony founder Jason Read said his company too tracked a half-hour distribution affecting access to several popular sites on the same day from the East Coast. Later the disruption was spread to West Coast and Europe too.

CloudHarmony is owned by Gartner Inc. and is an internet performance monitoring company.

In recent months it has been noticed the DDoS attacks have been growing in size as well as frequency and the claims of hackers cannot be ruled out considering the Friday’s attacks of a new level.

Cybersecurity firm Verisign released a report saying the attack perpetrated during the second quarter of 2016 and it was peaked at just 256 billion bits per second.

In September a similar attack blocked the website of security journalist Brian Krebs and it was clocked in at 620 billion bits per second.
