Computer Weekly: On Thursday, Twitter went down for about two hours. According to company officials, the outage was caused by infrastructure failures at its main data center and its backup site at the same time. "I wish I could say that today’s outage could be explained by the Olympics or even a cascading bug. Instead, it was due to this infrastructural double-whammy," said Twitter's Mazen Rawashdeh. "We are investing aggressively in our systems to avoid this situation in the future."
Last month, Twitter experienced downtime caused by a software bug.
Twitter is expecting a large increase in traffic on Friday when the Olympic games begin.
