By 2:27 a.m. Pacific time, a little more than two hours after it began investigating the incident, the company reported that it had applied initial mitigations and recommended customers retry failed requests, warning that there may be additional latency as some services had a backlog to work through.
Three hours after it began its investigation, the company reported that global services and features reliant on US-EAST-1 had recovered and promised further updates when it had more information to share.
Cloud dependencies
While this outage was quickly fixed, it shows that even in the cloud there are single points of failure that can have worldwide consequences.
A few months ago, it was Microsoft with egg on its face, as a problem in Azure’s US East region rippled out to affect other organizations. Before that, a series of outages at IBM Cloud had customers wondering if they had made the right design choices. The third, shorter, outage affected 54 IBM Cloud services.
