Cooling related failure (in Google London DC)
Oracle also had issues around the same time:

It's kind of annoying when clouds use availability zones as such an opaque thing, it's not possible to map a zone from one cloud to another and potentially your failure domains overlap.Shameless self promotion: I have a map of all the cloud regions (but not going into as much detail as availability zones): https://cloud-regions.bodge.cloud -- the clouds just don't publish the data.
