Major Cloud Outages

Last Update:  10 January 2021 - Final Update, will not be tracking outages in 2021

A running collection of cloud related outages/incidents (2013-present) with associated news articles and provider responses. Also began noting newsworthy cyberattack outages in late 2016 as more seemed to be popping up in feeds/alerts.

Outages listed may be somewhat spotty/random, simply picked up by various scans, alerts or feeds.  Links to articles and incidents may also break over time, but still may be useful to those evaluating Cloud Service Providers.  Suggestions always welcome!
