During the period of Thursday 22nd of October at 07:10 - 15:55 CEST, Umbraco Cloud suffered an issue with our hosting management system, which caused downtime and/or general instability for several hosted websites on the platform.
This post mortem will outline the events as they occurred, give details on the root cause and explain what steps we are taking to improve and prevent similar incidents based on these learnings.
Summary and root cause
On October 22nd, 2020 at 07:10 CEST websites on Umbraco Cloud started to become unavailable with timeout errors due to an issue with a central component of our hosting management system.
We were able to execute an emergency patch at 07:49 AM CEST, and a full recovery for all sites was initiated immediately.
Recovery timeline
Site recovery timeline:
65% of sites recovered before 09:00 CEST
95% of sites recovered before 12:30 CEST
100% of sites recovered before 15:55 CEST
Follow Up
Additional root cause analysis was completed Friday, October 23rd and improvements to infrastructure and internal processes were made. This includes more thorough monitoring and prioritisation of fixes related to this issue in our hosting platform which we are now working on implementing in order to prevent future related incidents from happening as well as shortening the lead time from detection to deployment of critical patches if necessary.
We apologize for the inconveniences this incident has caused you and your customers. We want to underline that our work to ensure stable operations on Umbraco Cloud does not end with this update but is ongoing and is of the highest priority to us.
