VMware Causes Second Outage While Recovering From First
jbrodkin writes "VMware's new Cloud Foundry service was online for just two weeks when it suffered its first outage, caused by a power failure. Things got really interesting the next day, when a VMware employee accidentally caused a second, more serious outage while a VMware team was writing up a plan of action to recover from future power loss incidents. An inadvertent press of a key on a keyboard led to 'a full outage of the network infrastructure [that] took out all load balancers, routers, and firewalls... and resulted in a complete external loss of connectivity to Cloud Foundry.' Clearly, human error is still a major factor in cloud networks."
I didn't get the sense from reading the linked analysis that it was necessarily a single key-press. It reads like this:
This was to be a paper only, hands off the keyboards exercise until the playbook was reviewed. Unfortunately, at 10:15am PDT, one of the operations engineers developing the playbook touched the keyboard. This resulted in a full outage of the network infrastructure sitting in front of Cloud Foundry. This took out all load balancers, routers, and firewalls; caused a partial outage of portions of our internal DNS infrastructure; and resulted in a complete external loss of connectivity to Cloud Foundry.
My sense is that "touched the keyboard" doesn't literally mean "touched a single key on the keyboard", but actually means "ignored the hands-off-the-keyboard part of the exercise, and executed some commands".
But who knows, I could be wrong... I'm sure hoping I'm not!
