Wikipedia knocked offline by cut cable
Wikipedia was offline yesterday afternoon after a fibre cable was cut.
The site went down about 3;15pm for an hour, with the mobile site offline for more than two hours.
Wikimedia’s director of technical operations CT Woo said the network connectivity between its two data centers – one in Virginia, the other in Florida – had disappeared. Upon checking with our network provider, they informed us that the outage was caused by a fiber cut between the two data centers,” he said in a blog post.
The two data centers have a pair of fibre links for redundancy, and Wikimedia is asking its network provider why services went down.
“We do operate two 10Gbit/sec separate fibers between the data centers,” Woo said. “We are now working with our network provider to determine how and why we were impacted by that fiber cut when we are supposed to have redundancy in our network. We are still waiting for their full report.”
The site was pushed back online by rerouting all traffic to the Florida data center, with the site yet to flip back to using both data centres.
