I wonder, is this (still) common these days? Having a datacenter on a single physical cable?

- acveilleux 11y agoTo be fair, they're setting up the backup link. This DC, like many others, is well out of the way so running distinct fiber is lengthy process and even localizing fault and getting crews on site can be a drag. The location of Beauharnois probably being chosen because there's a Hydro plant there with 1903 MW of installed capacity.
- deepsun 11y agoAt Google -- no. At OVH -- yes, apparently. Google have it's own outages, caused mostly by a network config change or software update, but not from fiber cuts.
- tomschlick 11y agoPlus Google has a shit ton of redundancy. I remember watching a video about their site reliability team. Their job is to test worst case scenarios and they can/will cut an entire datacenter out of a service's (gmail, drive, etc) pool to see what happens.
- oasisbob 11y agoTheir exercises are also excellent at including the full organization in DiRT, not just engineering. eg, Just because someone is "authorized" to spend six-figures for scheduling a diesel delivery doesn't mean they will. _Weathering the Unexpected_ https://queue.acm.org/detail.cfm?id=2371516 https://queue.acm.org/detail.cfm?id=2371516
