April 21, 2021 Automation Cloud Outage Postmortem | UiPath

Customer impact

On April 21, 2021 from 1:26 am UTC until 2:56 am UTC, customers accessing Automation Cloud™, UiPath Automation Hub, and all other UiPath cloud services saw a very high rate of errors. At peak, our authentication service was returning up to 33% errors. However, since some scenarios require multiple calls to the authentication service, the impact to customers was even higher. Robot authentications were also failing at this time.
