UltraDNS Service – 90 Minutes Let-Down

UltraDNS, service went down recently pulling down with it several of the popular sites which included Netflix and Expedia, the outcome of the 90 minute let-down. UltraDNS is said to be one of the top providers in the web content delivery space. Together with competitors like Akamai and CloudFlare, it tends to play an important role in directing as well as managing web traffic for businesses which rely on the series for website speeds and protection against DDoS attacks. Developed in 2006 by Neustar, the company has an information service company based in Sterling, Va. Members of the UltraDNS support team at first had indicated that the problem had stemmed from the Denial of Service – DDoS attack where hackers tend to flood the service with traffic till it tends to collapse due to the load. But as per Ms Wyss, Chief Information Officer, on further investigation, claimed that the problem was not caused by a DDoS assault but instead was the result of a technical malfunction. However, the system failure was restored immediately but created a ripple effect throughout the World Wide Web as several of the companies essentially depended on UltraDNS’ cloud service in order to keep their sites up and functioning.

Customers/Administrators Posted Complaints through Twitter

Some of the irritated customers as well as administrators had posted their complaints through Twitter. The failure recently was the second time in two years where the service had gone down according to a company in Minneapolis, Dotcom Monitor, which tends to monitor web speeds and performance. UltraDNS, in January 2013, had faced a similar failure which affected customers across the globe. The statement that UltraDNS seemed to be under attack was not unreasonably given an increase over the past 18 months. This was due to high volume DDoS attacks which exploit the Internet’s switchboard system known as the Domain Name System or DNS, to intensify the outbreaks. Several of these attacks have been from China against China-specific websites, according to the chief executive at CloudFlare, Matthew Prince.

DDoS Attempting Forged Traffic Requests

The DDoS attackers are now attempting to make forged traffic requests which tend to appear genuine thus making it difficult for companies to eliminate. According to Mr Prince, these types of attacks tend to really come at high rates which only the most secured and toughest websites could fend them off. In some instances, there could be around 500 million traffic request per second. While Netflix faced a down time due to UltraDNS failure, millennial from Twitter world posted funny comments. Some other also attributed that the end of Netflix would have serious effects on increasing population as Dalibor (@DaliDimovski)stated that Netflix is down and now no babies will be born on July 15, 2016, while a twitter user, spooky Giselle (@Blushedhes) stated that Netflix is down I guess this is how the world is going to an end. Netflix on the other hand offered an apology to their audiences and tweeted that they are aware that members are facing issues streaming on all devices and are working to resolve the issue.
