At least one major data center disconnected from the grid and went to generator power, prior to the rolling blackouts. The motivation was not stated, but it seems likely that they were requested to do so as part of the voluntary interruption efforts. No interruption of service was seen.
In a conversation with an MFS engineer today I mentioned the problems in the Bay area. He previously worked for SNET (Southern New England Telephone, now part of SBC) for many years and said it was standard practice for them to disconnect COs from the grid and run off generator power for hours or even a day or two during the summer season. I was under the impression that these power shortages were the result of less over-engineering on the part of power companies due to deregulation but maybe this isn't such a new situation after all?
