On the same day Cisco released patches for multiple operating system and software vulnerabilities, the network routing and switching vendor suffered an outage that knocked the Cisco.com offline for about three hours.

Cisco site does dark on patch day The outage, blamed on "human error [that] caused an electrical overload on the systems," affected support services, including access to the security patches released by Cisco.

The official word, via Cisco's blog (which survived the outage because it was on a different network):

Service to Cisco.com has been restored and all applications are now fully operational. The issue occurred during preventative maintenance of one of our data centers when a human error caused an electrical overload on the systems. This caused Cisco.com and other applications to go down. Because of the severity of the overload, the redundancy measures in some of the applications and power systems were impacted as well, though the system did shut down as designed to protect the people and the equipment. As a result, no data were lost and no one was injured. Cisco has plans already in process to add additional redundancies to increase the resilience of these systems.

In all, Cisco issued four security advisories an an alert for one security response incident on the day of the outage.

The advisories all affect IOS and one affects Cisco Unified Communications Manager as well. The skinny:

  • Ouch

    Someone needs to put the sign back on the rack..."Do NOT plug the vacuum cleaner into the rack outlet"

    • Re:Ouch

      It must have been a vacuum because that outage most certainly sucked.

    • i dont believe human error could cause a power surge like that

      ridiculous version of events most likely.

      probably a ddos attack

      • Unlikely a DOS

        It was unlikely a DOS since, if we were to assume that the image of www.cisco.com response time is correct, there was no increasing response time before the incident. It would have been an immediate failure within the farm. Likely a design flaw.

        If it was a single human error, then i can see someone on the breadline afterwards.
