    Global Outage (cooling failure and DNS)



    Due to an overheating problem in our European data center many of our servers turned off to protect themselves. As this impacted all Wikipedia and other projects access from European users, we were forced to move all user traffic to our Florida cluster, for which we have a standard quick failover procedure in place, that changes our DNS entries.

    However, shortly after we did this failover switch, it turned out that this failover mechanism was now broken, causing the DNS resolution of Wikimedia sites to stop working globally. This problem was quickly resolved, but unfortunately it may take up to an hour before access is restored for everyone, due to caching effects.

    We apologize for the inconvenience this has caused.

    Wikipedia down after server meltdown..

    Wikipedia was offline Wednesday afternoon after an overheating problem at the online encyclopedia's European data center.

    Wikipedia's technical blog said the site's servers shut themselves down to avoid damage from the heat.

    Administrators tried to shift traffic to a cluster of servers in Florida, but "it turned out that this failover mechanism was now broken, causing the DNS resolution of Wikimedia sites to stop working globally," according to the blog.

    "This problem was quickly resolved, but unfortunately it may take up to an hour before access is restored for everyone, due to caching effects," the blog said.

    Trying to access wikipedia.com and wikipedia.org at about 2:45 p.m. ET produced a navigation error message.

    One post to Wikipedia's technical blog, by a user named Jimmy, found some humor in the situation: "And so we remember Thursday, March 25, 2010 as the day every English speaking student failed their research papers."
