Data Center Problems Caused Twitter Outage – CIO Today
Twitter blamed systems failures -- not a crush of traffic around the Olympic games -- for an outage last Thursday that saw people around the world experience problems accessing the micro blogging site for more than an hour.
The San Francisco-based company said the outage was caused by a "noteworthy" double failure in its data centers. When one system fails, a parallel one is meant to take over, but two systems coincidentally stopped working at around the same time, Twitter said.
"I wish I could say that today's outage could be explained by the Olympics or even a cascading bug," Mazen Rawashdeh, VP of engineering, said in a statement apologizing to users. "Instead, it was due to this infrastructural double-whammy."
