[outages] Linode outage in Newark, NJ starting at 3:30 pm

[Alex Rubenstein]

The fault was related to an automatically operated circuit breaker on one of several generators. It would not close automatically, and had to be persuaded, which took some time. Further details will be made available to customers as soon as the post-event investigation is complete.

It is common to have not only strings of batteries but an ATS, or automatic transfer switch. In this case, it sounds like the fault was on the ATS side of the plant based on the IR below.

Is it common practice to have an array of batteries in between the colo and the generators to give you time to start the generators?

This is the incident report from NAC:
Subsequent to the utility power failure at our Cedar Knolls facility the generator that powers systems A and D did not start automatically.
Manual intervention was required to get generator power running.
Unfortunately before the generator was manually engaged customers on these systems experienced a complete power loss. We are still investigating why the generator did not engage automatically.Utility power has been restored, and transfer back to utility was successful.
