"We are sorry," Twitter said via a blog post. "Many of you came to Twitter earlier today expecting, well, Twitter. Instead, between around 8:20 a.m. and 9:00 a.m. PT, users around the world got zilch from us. By about 10:25 a.m. PT, people who came to Twitter finally got what they expected: Twitter. "
The social networking site said the outage came from within its data centers.

"Data centers are designed to be redundant: when one system fails (as everything does at one time or another), a parallel system takes over," Twitter said. "What was noteworthy about today’s outage was the coincidental failure of two parallel systems at nearly the same time."
The outage — which was first noticed at around 11:15 a.m. ET and had been down for about an hour — didn’t even display the company’s typical “fail whale” logo it typically posts during down times. The platform slowly come back for some across the U.S.
“We’re aware of the issue and are looking into it,” a Twitter spokesperson told Mashable. “We will let you know when we have an update, and keep an eye on status.twitter.com for updates as well.”
The company also posted a note on its blog informing members of the issue: “Users may be experiencing issues accessing Twitter,” it said on the site. “Our engineers are currently working to resolve the issue.”
