Twitter was down for quite a while today. It was pretty annoying to say the least. It's a free social network, so I can't really complain, but it's also pretty wild how often we use it as journalists (and, I suppose, as social beings). It's the first thing I check when I wake up in the morning and it keeps me in touch with the world, my friends, colleagues and global news.

"We are sorry," Mazen Rawashdeh, Twitter's vice president of engineering said in a blog post. "Many of you came to Twitter earlier today expecting, well, Twitter. Instead, between around 8:20am and 9:00am PT, users around the world got zilch from us. By about 10:25am PT, people who came to Twitter finally got what they expected: Twitter. The cause of today's outage came from within our 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. What was noteworthy about today's outage was the coincidental failure of two parallel systems at nearly the same time."

Rawashdeh said Twitter is investing aggressively in its systems so that a similar outage does not occur. "On behalf of our infrastructure team, we apologize deeply for the interruption you had today," he added.

Apology accepted.
