Facebook experienced an outage that left some people unable to connect to the site. With one billion monthly active users, you can imagine that even the slightest hiccup is going to be noticed and that people are going to complain and complain they did.
Still, the outage only affected some parts of Europe and it lasted less than an hour even for the worse affected.
Facebook took the blame for the problem, a DNS configuration test, designed to optimize traffic, i.e. send people to the closest and freest possible server, caused the error.
"Earlier today we made a change to DNS as part of a traffic optimization test, and that change resulted in some users being temporarily misrouted," Facebook explained.
"We detected and resolved the issue immediately, but a small number of users located primarily in Western Europe experienced issues accessing the site while the DNS addresses repopulated. We are now back to 100 percent, and we apologize for any inconvenience," it said.
