Two service breakdowns within the course of several hrs shakned Twitter on Thursday, since users throughout the world noted considerable down-time as well as sluggish service over both Twitter's website and mobile applications.
In the midst of rumours that Twitter had been disabled by a hacker attack, Twitter blamed the interruption to its most severe episodes in recent months - on a "cascading bug" in one of its infrastructure features.
"One of the features of this sort of a bug is that it can carry a considerable impact on all users, globally, that was the situation today," Mazen Rawashdeh, a Twitter vice president of engineering, authored in a blog post on Thursday mid-day, following regular service started again.
"We are actually running a complete evaluation in order to make sure that we can prevent this chain of events in the future," he added in.
Twitter's statements came up after UgNazi - an rising hacker that recently gathered hype for breaking up Cloudflare chief executive Matthew Prince's personal Google email account - took responsibility for the service dysfunction in an email to Reuters, telling it formed a distributed denial-of-service attack in opposition to Twitter since company's services for the Cyber Intelligence Sharing and Protection Act.
